Abstract

A mechanically tuned broadband Kerr frequency comb (KFC) is demonstrated in a Whispering Gallery Modes (WGM) microresonator. Due to their tiny mode volumes (V) and ultra-high Q factor ~ 108, optical WGM microresonators exhibit low threshold power for nonlinear phenomena (scales as V/Q2). Here we focus on the production and mechanical tuning of a 300 nm wide Kerr Frequency Comb (KFC) in silica stretchable microspheres. The ability to tune the KFC source – and hence to lock it to a narrow atomic line – makes it suitable as the basis for a future miniature atomic clock.
