The new amplifier offers high performance, is compact enough to integrate into a chip just millimeters in size, and – crucially – does not generate excess noise.</b></p>​<span style="background-color:initial">&quot;This could be compared to switching from older, dial-up internet to modern broadband, with high speed and quality,&quot; says Professor Peter Andrekson, Head of the Photonics Laboratory at the Department of Microtechnology and Nanoscience at Chalmers.</span><div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">​Optical communication makes it possible to send information over very long distances. The technology is useful in a range of applications, such as space communication and in fiber optic cables for internet traffic.</span><div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><img src="/sv/institutioner/mc2/nyheter/PublishingImages/Spiral%20waveguide.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:260px;height:146px" />With communication based on light, rather than radio waves, we could, for example, quickly send high-resolution images from Mars. The information, carried by laser beams, could be sent with high speed from a transmitter on the planet to a receiver on Earth or on the Moon. Optical communication also allows us to use the internet around the world – whether the signal is transferred in optical fiber cables under the seabed or transmitted wirelessly.</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">Because the light – carrying the information between two distant points – loses power along the way, a large number of optical amplifiers are needed. Without amplifiers, up to 99 percent of the signal in an optical fiber cable would disappear within 100 kilometers.</span></div> <h2 class="chalmersElement-H2"><span>A constant battle against excess noise</span></h2> <div><span style="background-color:initial">A well-known problem in optical communication, however, is that these amplifiers add excess noise that significantly impairs the quality of the signal you want to send or receive. Now, the Chalmers researchers present an extremely promising solution to an obstacle that has existed for decades.</span><br /></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">“We have developed the world's first optical amplifier that significantly enhances the range, sensitivity and performance of optical communication, that does not generate any excess noise – and is also compact enough to be of practical use,” says Ping Zhao, Postdoc at the Photonics Laboratory at Chalmers and one of the lead authors of the scientific paper, now <a href="" target="_blank">published in Science Advances​</a>.</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">The light amplification in the project is based on a principle known as the Kerr effect, which so far is the only known approach that amplifies light without causing significant excess noise. The principle has been demonstrated before, but never in such a compact format– previous versions were too bulky to be useful.</span><div>The new amplifier fits in a small chip just a few millimeters in size, compared to previous amplifiers that have been several thousand times larger.</div> <h2 class="chalmersElement-H2"><span>Tiny, quiet, and with high performance</span></h2> <div><span style="background-color:initial">Additionally, the new amplifiers offer a level of performance high enough that they can be placed more sparingly, making them a more cost-effective option. They also work in a continuous wave (CW) operation rather than a pulsed operation only.</span><br /></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><img src="/sv/institutioner/mc2/nyheter/PublishingImages/Chip.jpg" class="chalmersPosition-FloatRight" alt="Chip" style="margin:5px;width:260px;height:215px" />“What we demonstrate here represents the first CW operation with an extremely low noise in a compact integrated chip. This provides a realistic opportunity for practical use in a variety of applications. Since it’s possible to integrate the amplifier into very small modules, you can get cheaper solutions with much better performance, making this very interesting for commercial players in the long run,” says research leader Peter Andrekson.</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">The new results also open doors to completely new applications in both technology and science, explains Peter Andrekson.</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">“This amplifier shows unprecedented performance. We consider this to be an important step towards practical use, not only in communication, but in areas including quantum computers, various sensor systems and in metrology when making atmospheric measurements from satellites for Earth monitoring.”</span></div> <h2 class="chalmersElement-H2">More about the research:</h2> <div><ul><li><span style="background-color:initial">The scientific article <a href="" target="_blank" title="Overcoming the quantum limit of optical amplification in monolithic waveguides">&quot;Overcoming the quantum limit of optical amplification in monolithic waveguides&quot;​</a> has been publis​hed in Science Advances.

But to achieve this, new and more advanced radar systems are required for more accurate navigation. Now, a Chalmers-led research project has developed radar components with a unique level of performance that can contribute to reducing the climate impact.</b></p>​<span style="background-color:initial">A European target for reducing the climate impact of aviation states that aircraft that are put into operation after 2020 should have 50 percent lower carbon dioxide emissions compared to those that put into operation in 2000. Of this improvement, more efficient air traffic management systems are estimated to be able to contribute about 10 percentage points. Newer, more efficient systems, which can facilitate better flying in rain and fog, are an important measure to reduce carbon dioxide emissions and achieve the goal. When aircraft can fly more directly towards their destination and avoid interrupted landing attempts due to bad weather, unnecessary emissions can be reduced.</span><div><br /><span></span><h2 class="chalmersElement-H2">Components with the right properties have been missing</h2> <div>A precondition for this is to upgrade the air traffic control systems with better radars on the aircraft themselves. These radars operate in the assigned frequency range 93–100 gigahertz. The problem is, radar components in this frequency range, with properties that allow large-scale use and are sufficiently cost-effective, are not currently commercially viable. But now, after almost three years of research, the Chalmers-led, European project is the first in the world to demonstrate precisely this type of component.</div> <div>“Aviation has a major climate impact and so it is important to work with as many measures in parallel to reduce this impact. It feels great to be able to contribute to more sustainable flying in the future,” says Dan Kuylenstierna, Associate Professor at the Department of Microtechnology and Nanoscience at Chalmers and leader of the project.</div> <div><br /></div> <h2 class="chalmersElement-H2">The challenges of generating high transmitter power at high frequency</h2> <div>The radar components developed through the project are similar to those in self-driving cars. But to be able to be used in aircraft, especially in rain and bad weather, the transmitter power needs to increase significantly. This in itself is a difficult task, as the frequencies used in aviation are higher than in cars – and the higher the frequency, the more difficult it becomes to generate high transmitter power. To solve this problem, the research project developed new circuits and encapsulation methods. This means that the technology can now be integrated into the new aircraft's air traffic control system in a way that is both cost-effective and reliable. </div> <div><br /></div> <div>The scientific results of the research project have been published at international conferences:</div> <div><a href="" target="_blank" title="Link to publication: A 24 GHz Sub-Harmonically Pumped Resistive Mixer in GaN HEMT Technology"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />A 24 GHz Sub-Harmonically Pumped Resistive Mixer in GaN HEMT Technology</a></div> <div><span style="background-color:initial"><a href="" target="_blank" title="Link to publication: A low phase noise W-band MMIC GaN HEMT oscillator"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />A low phase noise W-band MMIC GaN HEMT oscillator</a></span><br /></div> <div><br /></div> <div>The project has also led to a patent application.​</div> </div>Fri, 09 Jul 2021 11:00:00 +0200 a mind set on nano<p><b>​She’s a professor of applied quantum physics, a mother of three and speaks five languages. As the leader of the interdisciplinary Nano Excellence Initiative, Janine Splettstoesser now wants to create one of Europe's top nano-centers with the goal of addressing the biggest challenges facing the society. But when it comes to the proudest career moments, she’d rather speak about her students. &quot;When a PhD student gives a really good defense on their dissertation and can continue to work on what they really like and subsequently grow as a researcher. That makes me really proud.”​</b></p>​<span style="background-color:initial">We meet in the department’s family room. It's Easter break and Janine’s 6-year-old son Paolo has come along. He immediately starts pulling out building kits and tricky games from the shelves while Janine takes a seat at a destinated workplace across the room. An empty desk and an ordinary laptop. A mind-blowing thought to an outsider that this is all that is needed for a professor of applied quantum physics when trying to juggle lectures, seminars, conferences and supervision of PhD students. Not to mention her own research.<br /><br /></span><div>Right now, it's all about the relationships between thermodynamics and quantum mechanics, what is normally referred to as quantum thermodynamics. Because, as Janine puts it, &quot;if you want to make new nanotechnology, it’s really good to know the underlying dynamics. And if you want a quantum computer that works well, you need to know what the energy consumption looks like and how best keep it cold during operation.&quot;  </div> <div><br /><strong>Janine’s many engagements at the department</strong> of Microtechnology and Nanoscience become clear within minutes. We’ve already touched on her teaching, PhD supervision and research. But as of 2021 she’s also the new Director of the Nano Excellence Initiative, a government-funded and interdisciplinary initiative, that includes three other departments besides her own - chemistry, physics, biology - with the joint ambition to promote research and development of nanotechnology at the university.<br /><br /></div> <div>&quot;My goal is to create a meeting place for nano-researchers at all levels, junior as well as senior. A kind of incubator for building collaborations, sharing ideas and networking,&quot; Janine explains. </div> <div><br />But that’s not all. Janine is also one of the initiators behind the family room we’re currently in. Why so? To enable researchers to combine a successful research career with family life. An important topic to Janine. <br /><br /></div> <div>&quot;If you have small kids and you need to go to a conference or perhaps to a meeting with collaborators, and you haven’t managed to solve childcare, you might face logistical problems. Which tends to lead to researchers having to limit their work, especially female researchers. A room like this can solve that sort of problem,&quot; Janine explains.<br /><br /></div> <div>And when asked if they’ve used the family room frequently, Paolo anticipates his mum: &quot;Hundreds of times!&quot;, he proclaims contentedly and continues to build on his maze.</div> <h3 class="chalmersElement-H3">The (un)obvious researcher </h3> <div>Janine somehow feels natural in her research role and in her field. She talks enthusiastically and joyfully about her research and her students. And as the oldest in a sibling group of five and with two researching parents, a mother in physics and a father in mathematics, it may seem strange that it was never self-evident to Janine to choose a research career. However, there were never any ruling expectations in terms of career paths. It was more a matter of a family culture that said you can become what you want to be. Nevertheless, the subject of physics did come up every once in a while at the dinner table, albeit in a discouraging way. </div> <div><br /></div> <div>“During high school, I had many different ideas about what I should study - architecture, design or medicine perhaps. And right after high school, I got involved in social work for a few years before I continued my studies. But I have always been into math and physics and solving problems. At the same time, I’ve also been interested in languages. As a matter of fact, my mum actually used to warn me: behave or else I’ll make you study physics &quot;, says Janine and laughs.<br /><br /></div> <div><strong>Perhaps a classic example of reverse</strong> psychology. Either way, it seems to have worked.<br /></div> <div>And in addition to her academic merits in physics, Janine also speaks five languages. No wonder if you take a look at her academic journey. A tour that has gone all over the European continent. <br /><br /></div> <div>She grew up near Düsseldorf and moved as a 20-year-old to Karlsruhe in southern Germany to study physics. During her master's studies, she did an exchange year in Grenoble, France, after which she returns to Germany to complete her master's studies. After that, straight to Italy to do her PhD at the Scuola Normale Superiore di Pisa, on &quot;Adiabatic pumping in interacting quantum dots&quot;. It’s during her PhD studies in Pisa that Janine's fascination for quantum physics really takes off. This is also where she meets her future husband, who at the time did his PhD in astrophysics. After that: post-doc at the University of Geneva while her boyfriend heads off to Hamburg. Then back to Germany to take on the position as professor of physics at the University of Aachen. In Aachen, Janine also receives a large research grant. A turn of events that in retrospect is looked upon as a significant milestone. <br /><br /></div> <div>“This is when I got to lead my own research group for the first time. I was able to recruit PhD students and post-docs and shape my own lectures. Freedom to do it my way, as it were. That’s when the idea that I could become an independent researcher was really brought to life.”<br /><img src="/SiteCollectionImages/20210101-20210631/Janine%202.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px 10px;width:300px;height:226px" /><br /><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial">Gothenburg calling</span><br /></div> <div>It’s easy to see life as a research couple travelling all over Europe through rose-tinted glasses.</div> <div>If she misses life as a round-the-clock researcher on the continent? Well, not really. </div> <div><br /></div> <div>&quot;You get fed up in the end. My husband and I had a long-distance relationship for ten years, it’s not something I recommend. Of course, it’s really fun and interesting to move around and constantly getting to know new cultures and learn new languages, but eventually it gets really hard to keep having to split up from friends and work just when you start to feel at home. Now, I’ve been in Sweden for a while, but I still feel like the dumbest parent at kindergarten. It still takes me forever to fill in even the simplest forms &quot;, she says and laughs.<br /><br /></div> <div><strong>So just over seven years ago</strong>, she finally settled down in Gothenburg and at Chalmers, at the time pregnant with the family's first child. Her significant other, who had a research position at Göttingen in Germany, was able to join up as a position opened up at the Department of Physics at Chalmers, just a stone's throw away.</div> <div>It wasn’t just coincidence that the choice fell on Chalmers. The five-year research project at RWTH Aachen had been completed and Janine and her husband had decided to stay in Europe. After some brief exploration of alternatives, she realized that Chalmers seemed to be a good place to conduct the kind of research she was particularly interested in. At the same time, she was approached by one of the professors of applied quantum physics at Chalmers at a conference, who suggested that Janine should come work with them. Said and done, Janine applied for a position as an Assistant Professor in Nanoscience at Chalmers. But she also applied for a research grant through Wallenberg Academy Fellows - Sweden's largest private career program for young researchers. It all ends up with Janine getting the position as well as the grant. And subsequently research funding for a five-year period, which since then has been extended through the Knut and Alice Wallenberg Foundation.<br /><br /></div> <div>“The Wallenberg's research grant has been really good for me in several ways. Besides funding my research, it has helped me build a good network as well as introducing me to the Swedish research environment.”<br /><br /></div> <div>But it turns out that life as a researcher at a Swedish university comes with even more perks. </div> <div><br />“Something I really liked from the beginning was that the culture here is much more equal and relaxed if you compare with, for example, some of the German universities. There, the hierarchies are very strong and the elbows sharper &quot;, says Janine.</div> <h3 class="chalmersElement-H3">The importance of good role models</h3> <div>And speaking of equality, it's almost hard not to mention the fact that Janine, as a female professor of quantum physics, stands out in the group. As a master's student, she was the only woman at the institute and at seminars. And when Janine first made her entrance into the Department of Applied Quantum Physics at Chalmers, she was once again the only woman. Today, six years later, she’s pleased to find that a third of the workforce is made up of women.<br /><br /></div> <div>There’s no doubt that academia needs good role models. Janine mentions times when female PhD students have approached her after speaks or lectures to express how much it means to see a woman – quite often with a baby under her arm - be an expert on the subject.</div> <div><br /><strong>Janine too has her own role models</strong>. She especially remembers her post-doc supervisor at the Institute of Theoretical Physics in Geneva, Professor M. Büttiker. A familiar name to many physicists. Through his humble and unpretentious style and his way of taking everyone's work seriously, regardless of position or academic rank, he has become a strong influence.<br /><br /></div> <div>&quot;To him, it didn’t matter if he was talking to a master's student or a Nobel Prize winner. He would invite his friends, people with names that we knew from our physics books. And he would introduce us as experts even though we were just post-docs. He simply took us all equally seriously. I was really inspired by him.”</div> <div><br />In that sense, it’s not very surprising that when Janine is asked to highlight her proudest moments in her career, she refers from listing academic advancements, professorships or publications. <br /><br /></div> <div>“I can’t deny that I was really proud when I finished my dissertation. But the proudest moments are probably when someone in my research group does a really good job. When a PhD student gives a really good defense on their dissertation and can continue to work on what they really like and grow as a researcher. That makes me really proud.”<br /><img src="/SiteCollectionImages/20210101-20210631/Janine%20och%20Paolo.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px 10px;width:300px;height:225px" /><br /><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial">From self-do</span><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial">ubt to pure grit</span><br /></div> <div>We decide to relocate to Janine’s office, a few stairs up. Paolo shows the way by skipping through the corridors. Janine’s years in Pisa seems to have made an impression. Under the office shelves filled with binders, books and paper is a well-used, coffee stained Italian espresso pot. Across the room hangs a large blackboard covered with never-ending calculations in white chalk. Just as one would expect from a professor of quantum physics.<br /><br /></div> <div>But has it always been easy? Have there never been any doubts?</div> <div><br />“When I did my PhD, I really had my doubts. Will I be able to do this? Am I smart enough? I was actually very close to giving up.”<br /><br /></div> <div>But Janine's plans to throw in the towel would soon be stopped. An old friend from school came to visit and changed her outlook on things completely.</div> <div><br />“She didn’t understand why I had doubts when I always had such good grades in school.  She told me that if I had doubts about being smart enough, just keep pretending to be clever for another two years and then, once that’s done, decide what I want to do,” Janine explains and laughs.<br /><br /></div> <strong> </strong><div><strong>Whether the argument worked</strong> is unclear, but Janine rode through the storm and came out on the other side. With honors. Since then, Janine has become quite used to dealing with tricky problems. </div> <div>So, what’s her driving force? <br /><br /></div> <div>“Definitely my curiosity. I face problems that I don’t understand almost every day. But then, you talk about the problem with colleagues and do some more reading and calculating until you get it. I’ve always liked to figure things out.”</div> <div><br />It’s obvious that Janine really likes her job. That she's in the right place. To her it’s all about making choices that feel right at the moment and trusting that you somehow end up in the right place. Like many physicists at the beginning of their career, Janine too thought she would focus solely on theoretical particle physics. But over time, the plan was revised.</div> <div><br />“I really like that I can do both fundamental research with heavy theoretical method development and at the same time think about exciting technical applications. It’s really cool to be able to sit and work theoretically and have the option to just go to the lab next door and talk to people to see if my calculations are correct.”<br /><br /></div> <div><strong>From the office window you </strong>can just barely see parts of the kindergarten yard. Janine lifts Paolo to make sure he gets the same view. Is it his baby brothers they can see from a distance, jumping around on the playground? They both agree; it’s Fabian and Mattia they spot. Perhaps it's the window view that makes Janine resume the topic of proud career moments. </div> <div><br />&quot;I just have to say that I’m incredibly proud that me and my husband actually managed to make this work in the end. That we can do what we are passionate about at work and, at the same time, have a fantastic family.”<br /><br />Text by: Lovisa Håkansson</div> Thu, 24 Jun 2021 00:00:00 +0200 story of OptiGOT - from research project to tech giant <p><b>​It was all a bit hush-hush as it was announced late last fall that the small startup OptiGOT from Gothenburg had been acquired by tech giant Nvidia. And the story that started in a Chalmers’ lab sometime 20 years ago has certainly entailed some valuable lessons. We met up with two of the founders of OptiGOT, Anders Larsson and Erik Haglund, to let them tell us about milestones, success factors and challenges along the way.  This is the story of OptiGOT.</b></p><div>​<span style="background-color:initial">It was at the end of November 2020 that chip company Nvidia announced that they had acquired Gothenburg-based startup OptiGOT. The deal had been completed already in April that year but was somewhat veiled in secrecy and was only made public six months later. At the time, neither sellers nor buyers wished to comment further on the deal in media and the purchase price was kept secret. However, on OptiGOT's LinkedIn page, the company's CEO, André Kelkkanen, made it clear that they were very pleased with the sale: “To use a football metaphor: Feels amazing. We join the best team in the world and get the chance to compete to win against the best competition in the world.&quot;</span></div> <div><br /></div> <div> </div> <div><strong>At the time for the acquisition</strong>, OptiGOT had grown into a cutting-edge start-up in high-performance surface-emitting semiconductor lasers, known as vertical-cavity surface-emitting laser (VCSEL). A technology that can be used in LIDAR and for high-efficiency and very fast data transmission via fiber cable. The method is groundbreaking and crucial for advanced big data testing, evaluation and analysis and made OptiGOT highly attractive to a range of big tech companies. Among those Nvidia, that since the 90s had been market-leading in computer and game graphics and now was getting established as a global player in AI and supercomputers. However, they weren’t the only ones trying to get OptiGOT’s attention. </div> <div> </div> <div><br /></div> <div> </div> <div><img src="/en/departments/mc2/news/Documents/Anders%20Larsson%20340x305.jpg" alt="Anders Larsson 340x305.jpg" class="chalmersPosition-FloatLeft" style="margin:5px 10px;width:200px;height:200px" /><span style="background-color:initial">“In 2019 and 2020, several companies showed interest in acquiring OptiGOT. One of these was Nvidia. At that point, it was really an easy choice. Nvidia is a fantastic and large international company that is doing brilliantly. They have muscles and have for some considerable time been market-leading in graphics processors for interactive graphics and in recent years, partly through acquisitions of various companies, also become leaders in AI and IT for e.g. supercomputers, autonomous machines, cloud and data centers, healthcare and life sciences, high-performance data processing, networks and self-driving vehicles,” says Anders Larsson, professor of Photonics at the Department of Microtechnology and Nanoscience, MC2, and one of four founders of OptiGOT. </span></div> <div> </div> <div><br /></div> <div> </div> <div>Today, just over a year after the sale, the team has become part of Nvidia and has expanded to seven people, all from Chalmers, six of whom originate from the Department of Microtechnology and Nanoscience.</div> <div> </div> <h3 class="chalmersElement-H3">With roots in industrial research</h3> <div> </div> <div>MC2's lab may be regarded as the starting point as OptiGOT's journey began sometime in the mid-90s. When the research project was unbundled in 2016, OptiGOT was considered a distillate of over 20 years of VCSEL research at Chalmers. With a team consisting of eleven doctoral students and four post-docs, the research was characterized for many years by a tenacity and a focus with clear short- and long-term goals. Something that the founders themselves believe has been crucial to the company's later success. But also the many collaborations with companies all over the world that marked the research years at MC2 are believed to have prepared them well for going into business. </div> <div> </div> <div><br /></div> <div> </div> <div>&quot;Eventually we became really good at this, world leading, you might say. Since the research was applied and industrial, we started to receive requests in 2000 from various companies for help with laser design, but also with the manufacture and testing of prototypes. For many years we declined, but at the beginning of 2015 we decided to give it a chance and started delivering designs through Chalmers Ventures,&quot; explains Anders.</div> <div> </div> <div><br /></div> <div> </div> <div><span style="background-color:initial"><img src="/en/departments/mc2/news/Documents/Erik%20Haglund%20340x305.jpg" alt="Erik Haglund 340x305.jpg" class="chalmersPosition-FloatRight" style="margin:5px 10px;width:200px;height:179px" />&quot;So already from the beginning we were able to identify some potential customers and shape a model for how</span><br /></div> <div>we would sell our technology. Because of that, we didn’t need to find or create a market for our &quot;product&quot;, which is a completely different challenge,&quot; adds Erik Haglund, former PhD student at MC2 and one of the founders of OptiGOT.</div> <div> </div> <h3 class="chalmersElement-H3">The birth of OptiGOT</h3> <div> </div> <div>The decision to test the business idea in collaboration with Chalmers Ventures in early 2015 would prove to be a good one. When the collaboration shortly after generated large orders from interested customers, it felt natural to get into business for real together. In 2016 OptiGOT saw the light of day, perhaps the biggest milestone of the journey for the four founders who, in addition to Anders and Erik, also includes Johan Gustavsson, associate professor at MC2 at Chalmers, and Chalmers Ventures. Shortly thereafter, a CEO was appointed, André Kelkkanen from Chalmers Ventures who at an early stage was able to complement the technical expertise with experience from entrepreneurship, business economics and business law. Something that Anders and Erik in retrospect are convinced of has been a major success factor in OptiGOT's progress. Two years later, the company moved into its own office, entailing the opportunity to shape an independence and an identity of their own. </div> <div> </div> <div><br /></div> <div> </div> <div><img src="/en/departments/mc2/news/Documents/Logga.jpg" alt="Logga .jpg" class="chalmersPosition-FloatLeft" style="margin:5px 10px;width:200px;height:179px" />&quot;It was really cool to take part in building a startup from scratch. Just to sit down and try to come up with a good name took a while. And then everything from designing the logo and website to buying IKEA furniture for the office,&quot; says Erik.</div> <div> </div> <div><br /></div> <div> </div> <div><strong>At the same time, the business grew </strong>to such an extent that several former photonics PhD students from MC2 were able to join up and develop the company further. And soon, takeover offers began to trickle in. And the rest is history.</div> <div> </div> <div><br /></div> <div> </div> <div>The journey of OptiGOT has been marked by well-founded decisions, no doubt. But there’s one crucial factor that may be difficult to control. Timing. In OptiGOT's case, the stars turned out to be aligned also on that point. In parallel with the progress of the research project and the formation of a company, the outside world seemed to go in a favorable direction. </div> <div> </div> <div><br /></div> <div> </div> <div>&quot;As we developed the research, the market for this type of laser also developed in a positive direction. From the mid-90s until the mid-00s, the market grew and was dominated by fiber optic data cables and various types of sensors such as optical data mice, for example. Since the mid-2000s, the market has grown rapidly as data centers around the world began to manage all data traffic in the cloud with fiber optic data cables, and as the laser technology began to be used increasingly for consumer electronics such as mobile phones, in terms of  camera focus and facial recognition, and other types of sensors such as laser radar for self-driving vehicles,&quot; says Anders. </div> <div> </div> <div><br /></div> <div> </div> <div>And there’s no sign of the market for laser technology slowing down. Quite the opposite. According to a recent report from Yole, the total market for VCSEL is projected to grow from $1.1 billion to $2.7 billion from 2020 to 2027, with a corresponding growth in data communication VCSELs from $277 million to $516 million over the same time interval.</div> <div> </div> <h3 class="chalmersElement-H3">From startup to tech giant</h3> <h3 class="chalmersElement-H3"> </h3> <div>However, like all journeys this too entailed challenges along the way. Moving from a research environment in academia to life as an entrepreneur was a tangible transition. For some, it involved a part-time position in two places, one at Chalmers and one at OptiGOT. A delicate balancing act, from time to time. The transition also involved stepping into a new culture.</div> <div> </div> <div><br /></div> <div> </div> <div>&quot;It was a challenge for those of us who came from academia to realize and learn that the conditions for industrial activities are quite different from those that apply to academic research. It doesn’t always have to be the best, good enough will do in many cases. But it should be possible to produce at an acceptable cost and work, “come rain or shine,” explains Anders.</div> <div> </div> <div><br /></div> <div> </div> <div><strong>Going from a small to large global company</strong> is a transition, as well. As the sale to Nvidia was realized, the startup of six employees merged into an international company with 20,000 employees in over 30 countries.</div> <div> </div> <div><br /></div> <div> </div> <div><img src="/en/departments/mc2/news/Documents/Gäng.jpg" alt="Gäng .jpg" class="chalmersPosition-FloatRight" style="margin:5px 10px;width:200px;height:179px" />&quot;It’s mostly positive, in terms of considerably more resources and opportunities to learn things that simply weren’t possible at OptiGOT, with insight into the entire chain, from components to complete systems. At the same time, it always takes time to learn how a large organization works in regards to processes and tools,&quot; says Anders.</div> <div> </div> <div><br /></div> <div> </div> <div>The saga of OptiGOT is a success story, no doubt. The journey may have been long but has been made possible by a highly dedicated and persistent research team, an early contact with industry and a continuous access to the labs at Chalmers. So, what are the most valuable lessons to be learned along the way? </div> <div> </div> <div><br /></div> <div> </div> <div>&quot;It's super important to bring people in who know how to start a company and who can manage the finances. So that time is dedicated to both dealing with technical stuff as well as customers. And it's important to have a good lawyer who can help out with contracts, in terms of how they work and how to write them. Someone who can sort out a first draft and double-check everything,&quot; says Erik.</div> <div> </div> <div><br /></div> <div> </div> <div>And Anders agrees:  </div> <div> </div> <div><br /></div> <div> </div> <div>&quot;Yes, it’s really important to bring in non-technical skills early on, i.e. entrepreneurship, business economics and business law. And you have to be passionate about this and be prepared to put in a lot of energy, patience and time. And you need to start &quot;simple&quot; in order to investigate and understand if the idea holds up. In other words, if there seems to be a demand.&quot;</div> <div> </div>Thu, 10 Jun 2021 00:00:00 +0200 for projects: AI in energy and climate research<p><b>​CHAIR, Chalmers Energy and ICT Areas of Advance are jointly investing in Data Science and AI in the Energy and Climate area.

They managed to demonstrate that superconductivity in a weak link can be controlled by applying voltages to electrostatic gates, in a similar way as semiconducting transistors are controlled by the field effect. This discovery has the potential to revolutionize the world of supercomputing, leading to a technology that would combine the advantages offered by semiconductors and superconductors.

The breakthrough provides a benchmarking tool for quantum computing of great value – and opens up for experiments in the exciting field of quantum thermodynamics.​​​</b></p><div><span style="background-color:initial">A key component in quantum computers are coaxial cables and waveguides – structures which guide waveforms, and act as the vital connection between the quantum processor, and the classical electronics which control it. Microwave pulses travel along the waveguides to the quantum processor, and are cooled down to extremely low temperatures along the way. The waveguide also attenuates and filters the pulses, enabling the extremely sensitive quantum computer to work with stable quantum states.  </span><br /></div> <div><br /></div> <div>In order to have maximum control over this mechanism, the researchers need to be sure that these waveguides are not carrying noise due to thermal motion of electrons on top of the pulses that they send.

Researchers from Chalmers University of Technology, Sweden, now present a game changing microcomb that could bring advanced applications closer to reality.​</b></p>​<span style="background-color:initial">A microcomb is a photonic device capable of generating a myriad of optical frequencies – colours – on a tiny cavity known as microresonator. These colours are uniformly distributed so the microcomb behaves like a ‘ruler made of light’. The device can be used to measure or generate frequencies with extreme precision.<br /><br /></span><div><span style="background-color:initial">In a recent article in the journal Nature Photonics, eight Chalmers researchers describe a</span><span style="background-color:initial"> new kind of microcomb on a chip, based on two microresonators. The new microcomb is a coherent, tunable and reproducible device with up to ten times higher net conversion efficiency than the current state of the art. <br /><br /></span><div><img src="/SiteCollectionImages/Institutioner/MC2/News/pr%20v%20torres%20mars%2021/Oskar_B_Helgason_pressbild.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:130px;height:130px" />&quot;The reason why the results are important is that they represent a unique combination of characteristics, in terms of efficiency, low-power operation, and control, that are unprecedented in the field,” says Óskar Bjarki Helgason, a PhD student at the Department of Microtechnology and Nanoscience at Chalmers, and first author of the new article.  <br /><br /></div> <div>The Chalmers researchers are not the first to demonstrate a microcomb on a chip, but they have developed a method that overcomes several well-known limitations in the field. The key factor is the use of two optical cavities – microresonators – instead of one. This arrangement results in the unique physical characteristics. </div> <div>Placed on a chip, the newly developed microcomb is so small that it would fit on the end of a human hair. The gaps between the teeth of the comb are very wide, which opens great opportunities for both researchers and engineers. <br /></div> <h2 class="chalmersElement-H2">A wide range of potential applications</h2> <div>Since almost any measurement can be linked to frequency, the microcombs offer a wide range of potential applications. They could, for example, radically decrease the power consumption in optical communication systems, with tens of lasers being replaced by a single chip-scale microcomb in data centre interconnects. They could also be used in lidar for autonomous driving vehicles, for measuring distances. <br /><br /></div> <div>Another exciting area where microcombs could be utilised is for the calibration of the spectrographs used in astronomical observatories devoted to the discovery of Earth-like exoplanets. <br /><br /></div> <div>Extremely accurate optical clocks and health-monitoring apps for our mobile phones are further possibilities.

This is a huge challenge, that requires maybe 5-10 years and an investment in engineering research. But I am convinced that it will happen,” says Victor Torres Company, who leads the research project at Chalmers. He continues: </div> <div>“The most interesting advances and applications are the ones that we have not even conceived of yet. This will likely be enabled by the possibility of having multiple microcombs on the same chip.

It functions as a ruler made of light, where the markers set the frequency scale across a portion of the electromagnetic spectrum, from the ultraviolet to the mid infrared. The location of the markers can be linked to a known reference. This was achieved in the late 90s, and it signified a revolution in precision metrology – an achievement recognised by the Nobel Prize in Physics in 2005. </div> <div><br /></div> <div>A microcomb is a modern technology, alternative to mode-locked lasers, that can generate repetitive pulses of light at astonishing rates. They are generated by sending laser light to a tiny optical cavity called a microresonator. Thus, microcombs have two important attributes that make them extremely attractive for practical purposes: the frequency spacing between markers is very large (typically between 10 – 1,000 GHz), that is much higher than the spacing in mode-locked laser frequency combs, and they can be implemented with photonic integration technology. The compatibility with photonic integration brings benefits in terms of reduction of size, power consumption and the possibility to reach mass-market applications. The large spacing between teeth means that microcombs can be used for novel applications, such as light sources for fiber-optic communication systems or for the synthesis of pure microwave electromagnetic radiation.</div> <div><br /></div> <div>The key to the new enhanced microcomb from Chalmers is that the researchers have used two microresonators instead of one. The microresonators interact with each other, similar to how atoms bind together when forming a diatomic molecule. This arrangement is known as a photonic molecule and has unique physical characteristics.</div> <div><br /></div> <div>Video recording from the lab: How to generate the microcomb.

In his PhD work, Hans also developed sensitive Hall sensors for magnetic field detection and contributed to the fabrication of a proof-of-concept terahertz detector, which potentially could revolutionize sensors used in next-generation space telescopes.<br /><br /></div> <div>&quot;Hans has developed a novel molecular doping technique for 2D materials, which has resulted in a patent and a high-impact publication in Nature Communications&quot;, says Ermin. <br /></div> <div>The director of the Graphene Centre is also keen to emphasize what the two award winning theses mean to the university at large. <br /></div> <div>&quot;Chalmers is often just seen as the coordinator of the big Graphene Flagship, but Samuel and Hans demonstrate how strong the actual 2D material research is at Chalmers.&quot;<br /><br /></div> <div>After receiving their prizes Hans and Samuel presented their award-winning theses. And besides enjoying the honor of winning the awards, it turns out also the prize money will come in handy. <br /></div> <div>&quot;As for the money, I'll probably save it until this pandemic passes and go travel somewhere with my wife&quot;, says Hans. <br /></div> <div>&quot;I will buy myself a good tablet to keep all my notes in the cloud and the rest of it will probably contribute to the budget needed to finally get my driving license&quot;, concludes Samuel. <br /><br /></div> <div>Samuel is currently doing his PostDoc at the University of Marburg in Germany and Hans is working for RISE where he continues doing active research on graphene-based primary metrology. </div> <div><br /></div> <div><strong>Text</strong>: Lovisa Håkansson</div> Mon, 01 Mar 2021 16:00:00 +0100 for ICT seed projects 2022<p><b> Call for proposals within ICT strategic areas and involving interdisciplinary approaches.​</b></p><h3 class="chalmersElement-H3" style="color:rgb(153, 51, 0)"><span style="color:rgb(153, 51, 0)">The application date has expired!</span></h3> <h3 class="chalmersElement-H3">Important dates:</h3> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div><ul><li><b>Submission date: </b><span style="text-decoration:line-through">April 29, 2021</span></li> <li><b>Notification:</b> mid-June, 2021</li> <li><b>Expected start of the project:</b> January 2022</li></ul></div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <h3 class="chalmersElement-H3">Background</h3> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div><b>The Information and Communication Technology (ICT) Area of Advance</b> (AoA) provides financial support for SEED projects, i.e., projects involving innovative ideas that can be a starting point for further collaborative research and joint funding applications. </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div>We will prioritize research projects that <strong>involve researchers from different research communities</strong> (for example across ICT departments or between ICT and other Areas of Advances) and who have not worked together before (i.e., have no joint projects/publications). </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div> </div> <div>Research projects involving a <strong>gender-balanced team and younger researchers</strong>, e.g., assistant professors, will be prioritized.
