Soliton regulation in microcavities induced by fundamental–second-harmonic mode coupling
Soliton regulation in microcavities induced by fundamental–second-harmonic mode coupling
Microcomb generation with simultaneous χ (2) and χ (3) nonlinearities brings new possibilities for ultrabroadband and potentially self-referenced integrated comb sources.However, the evolution of the intracavity field involving multiple nonlinear processes shows complex dynamics that is still poorly understood.Here we report on strong soliton regulation induced by fundamental-second-harmonic (FD-SH) mode …
