During the Optical Frequency Combs Workshop at Aston University, the lab tour took place. For this, a poster was prepared by Prof. Misha Sumetsky’s research group, where ESR1, Victor Vassiliev is working. The poster title is “SNAP microresonators fabricated with a flame and a heated wire”. It’s available here.




On 11-12 April a big Optical Frequency Combs workshop took place at Aston Institute of Photonic Technologies, Aston University. MOCCA was co-organiser of the event.

Leading researchers in the field of optical frequency combs science and technology discussed its fundamentals, applications, and future opportunities. The topics covered include the recent development of innovative sources based on lasers, waveguides and microresonators, novel nonlinear dynamics effects in optical resonators, and diverse applications of optical frequency combs in astronomy, quantum technologies, and photonic computing.
