Optical frequency combs are widely used for metrology, optical clocks, optical communications and sensors. In whispering gallery mode (WGM) microcavity resonators, geometrical features enable the four-wave mixing phase match condition to be satisfied. Hence, frequency comb generation is achievable. Geometrical dispersion of hollow structure WGM cavities can broaden the comb span to the visible range.
