Frequency combs in a microring optical parametric oscillator

Optics 2019-10-02 v1

Abstract

We report the soliton frequency comb generation in microring optical parametric oscillators operating in the down-conversion regime and with the simultaneous presence of the χ(2)\chi^{(2)} and Kerr nonlinearities. The combs are studied considering a typical geometry of a bulk LiNbO3_3 toroidal resonator with the normal group velocity dispersion spanning an interval between the pump and the down-converted signal. We have identified critical power signaling a transition between the relatively low pump power predominantly χ(2)\chi^{(2)} combs and the high pump power ones shaped by the competition between the χ(2)\chi^{(2)} and Kerr nonlinearities.
