Abstract: Laser frequency combs are remarkable photonic devices. Similar to a ruler, the spectrum of a frequency comb is made of evenly spaced optical lines. However, it is used to directly measure optical frequencies (instead of length) with astonishing precision. Frequency combs are enabling some of the most exciting scientific endeavors in the 21st century, like the calibration of astronomical spectrographs for searching Earth-like exoplanets or the development of the clockwork for an eventual redefinition of the SI unit of time. The impact of this technology was recognized in the Physics Nobel prize in 2005.

The core technology of a frequency comb is a mode-locked laser. Today, so-called microcombs constitute an alternative approach for the generation of a frequency comb on a chip-scale microresonator. Microcombs can be integrated with other devices using established techniques for semiconductor fabrication, holding the promise of delivering the performance of standard mode-locked lasers but on a microphotonic chip. In addition, the teeth separation in microcombs is orders of magnitude larger than what is possible with other technologies. As a result, microcombs are enabling a myriad of applications, from optical telecommunications to lidar.

In this lecture, I will give an overview of our research at Chalmers in the field of microcomb science and technology. I will put the research results in a historical context, accounting for some of the most relevant developments in the field in the last couple of decades. I will finalize by giving a forward-looking overview of what this exciting field may enable for the coming years.
