Optical Frequency Combs in Quadratically Nonlinear Resonators [PDF]
Micromachines, 2020 Optical frequency combs are one of the most remarkable inventions in recent decades. Originally conceived as the spectral counterpart of the train of short pulses emitted by mode-locked lasers, frequency combs have also been subsequently generated in continuously pumped microresonators, through third-order parametric processes.

Phase Noise Reduction of an Optical Frequency Comb Using a Feed-Forward Heterodyne Detection Scheme
IEEE Photonics Journal, 2016 A novel feed-forward phase noise reduction scheme is introduced to reduce the phase noise of an optical frequency comb. The phase noise of a single comb line is measured using a heterodyne technique, and the inverse of this signal is then applied to the ...
