Millions to the Information and Communication Technology of the future

Anders Larsson and Jan Stake at MC2 are two of the Chalmers researchers who receive funding from the Swedish Foundation for Strategic Research (SSF). "We will now, for the first time, be able to channel monitoring and adaptivity of signal parameters in real time to sustain the highest possible interconnect data throughput over temperature," says Anders Larsson, professor of photonics.
SSF distributes close to SEK 200 million to six different projects in a research effort for faster and energy-efficient Information and Communication Technology (ICT). The six projects are financed with between SEK 28 and 35 million each for five years, starting 2021.
"Together, they have the potential to strengthen Sweden’s position in important areas for our industry and competitiveness," says Jonas Bjarne, research secretary at SSF, in a press release.

Larsson explains that optical interconnects are increasingly used to provide the interconnect bandwidth, bandwidth density, and energy efficiency needed in high-performance computing systems, whether being a large-scale datacenter or a single high-capacity signal processing unit. Future optical interconnects for datacenters, automotive networks, and advanced radar systems will require operation under more harsh conditions, at much higher temperatures and over a much larger temperature range.
"This is a considerable challenge and calls for the development of a new generation high-temperature optoelectronic components and electronic ICs, more tolerant to temperature variations, and for exploring adaptivity to compensate for large variations of the optical channel response," says Anders Larsson.

The project will enable this by bringing together leading expertise in optoelectronics, electronics, and optical communication. It involves four research groups at Chalmers led by Anders Larsson, Peter Andrekson, both at MC2, Lars Svensson at the Department of Computer Science and Engineering, and Henk Wymeersch at the Department of Electrical Engineering.
"We will develop a new generation high-temperature lasers and driver/receiver ICs, tolerant to temperature variations, and explore, for the first time, channel monitoring and adaptivity of signal parameters in real time to sustain the highest possible interconnect data throughput over temperature," explains Anders Larsson.

The project also involves close collaboration with Nvidia, Volvo Cars, and Saab Surveillance, companies in Göteborg dependent on this technology for future products in their markets: datacenters, vehicles, and radars.

"In the project, we want to demonstrate telecommunications at frequencies close to 1 THz, which has not been done before in Sweden. Achieving the goal requires new combinations of different technologies, and we collaborate with expertise at Chalmers, where they have developed some of the most prominent semiconductor devices for THz frequencies," says Joachim Oberhammer in an article on KTH's website.

Jonas Bjarne, research secretary at SSF, underlines that four of the six proposed projects have the theme of energy efficiency in common.
"This is strategically very important as the ICT sector’s dramatically increasing energy consumption is receiving increasing attention,", he says.

Besides Larsson and Stake, Per Stenström, professor at the Computer Engineering division at the Department of Computer Science and Engineering, is granted SEK 28 086 883 in the same announcement.
