Microresonator frequency combs and crystals of light

Abstract

Microresonators, with highly compact size, strong nonlinearity and the ability to tailor the dispersion, have attracted great attention in the last decade. Microresonator-based frequency combs (microcombs) have accelerated the progress in the next-generation applications, including range sensing, quantum commutation, spectroscopy, etc. The ring structure limits the light circulating in the cavity to the resonant frequencies. The microcombs, resulting from the cascaded frequency conversions, are generated with the dual balances between nonlinearity and dispersion, as well as the gain and loss. This thesis starts with an overview of the frequency comb development and mechanism. We then report our theoretical studies of the microcomb generation and manipulation under different setups and materials.
