Experimental and numerical demonstration of tunable octave-wide four-wave mixing in dispersion engineered microresonators

摘要

We report on our experimental and numerical demonstration of tunable four-wave mixing (FWM) in dispersion engineered microresonators. In this paper, we focus on the engineering of higher-order dispersion, which enables the generation of tunable parametric oscillation far from the pump light. It allows us to obtain a localized comb structure, which is known as a clustered frequency comb. The numerical simulation agrees well with the experimental demonstrations, which confirms that the top-down dispersion engineering of a microresonator allows us to obtain phase-matched parametric oscillation deterministically.
