Abstract

Microresonator-based optical frequency combs (“microcombs”) have attracted lots of attention in the past few years thanks to their promising applications in telecommunications, spectroscopy, and optical clocks. The process of comb generation in microresonators can be modeled in the frequency domain using coupled mode equations and has recently been successfully described in the time domain using a nonlinear Schrödinger equation known as the Lugiato-Lefever equation. Time-domain approaches have brought many interesting insights for the understanding of microcombs. In this paper we present an intuitive frequency-domain model of microcombs that describes the overall structure of the spectra in terms of a few collective excitations of groups of neighboring comb lines, which we term “superoscillators.” This approach ties in nicely with the recently developed time-domain model based on soliton crystals and links the microcomb generation process with frequency response theory.
