Abstract :
Kerr optical frequency combs originate from the excitation of the whispering gallery mode of high Q monolithic resonators through the Kerr effect. In this presentation, we present the various models (spectro- and spatio-temporal) used to describe the nonlinear dynamics of these combs, which can feature structures such as bright and dark solitons, Turing rolls, or spatiotemporal chaos. We present a quantum formalism that allows to understand the phenomena of quantum correlations and squeezing in this system. We also discuss the relevance of this research for various applications such as time-frequency metrology, molecular spectroscopy, and ultra-low phase noise microwave generation.
