Kerr Frequency Comb in Microcavities: Fundamental and Application

The invention of optical frequency combs, which was celebrated by the 2005 Nobel prize in Physics, has made great impacts on precision metrology, optical clockwork, molecular fingerprinting, amongst others. Recent advances in high finesse Kerr-active microresonators have provided a promising platform for study of cavity nonlinear dynamics and offered a reliable route towards the vision of  chip-scale ultrashort pulses and frequency combs. Chip-scale optical frequency comb will become more instrumental in areas where compact footprint, low power consumption, large comb spacing, and access to unconventional spectral region are essential. In this talk, I will first introduce a new mechanism for achieving mode-locking of Kerr frequency combs in a normal dispersion microresonator; second, I will discuss our work on eliminating the cavity thermal perturbations from the generation dynamics of dissipative Kerr solitons; finally I will present our recent experiment that achieved nonlocal locking of two 19.6 GHz spacing Kerr soliton microcombs over metropolitan distance, which are exploited to achieve substantial saving of digital signal process operands for multi-channel coherent data receiving.
