The EPFL team is a pioneer in the field of microresonator-based optical frequency combs and spearheading the development of the field towards compact, scalable and robust chip-scale optical comb sources. EPFL has developed the photonic Damascene process enabling the fabrication of ultra-high-Q silicon nitride microresonators at a wafer scale. Thus EPFL will work on the fabrication and characterization of microresonator devices for the generation of optical frequency combs and will contribute to the work in WP3.

Prof. Tobias Kippenberg has 20 years of experience in nanophotonics and quantum optics, which places him at the forefront of the emergent revolution of quantum technologies and photonic integrated circuitry, and is in an excellent position to lead WP3.
