Advances in microwave generation using Kerr optical frequency combs

摘要

We report experimental studies on Kerr optical frequency generated with a a magnesium fluoride whispering gallery-mode disk-resonator. We particularly focus on microwave generation obtained after extracting the beat-note of the comb through fast photodetection. Primary comb patterns are excited through detuning the laser frequency with regards to the cold-cavity resonance, and they provide microwaves with different frequencies and high spectral purity.
