Abstract

Frequency comb generation in microring resonators with Kerr nonlinearity has been intensely studied in the last decade. These studies have demonstrated a plethora of novel solitonic effects with immediate applications in the precision measurements and optical signal processing [1]. Using nonlinear effects other than Kerr nonlinearity for comb generation is an active research area. In particular, Raman nonlinearity is ubiquitous in nature and its impact on Kerr frequency combs has attracted significant recent attention [1,2].
