Bistable solitons in third-harmonic generation frequency combs

Abstract

We present a theoretical model for describing dissipative solitons and optical frequency combs formation in a dispersive and nonlinear χ(3)-based cavity system that is phase-matched for third-harmonic generation. We consider the importance of the stability properties of the homogeneous solution in generating various types of multi-frequency combs, and demonstrate a novel type of bistable cavity solitons.
