Abstract
Abstract We theoretically study the nature of parametrically driven dissipative Kerr soliton (PD‐DKS) in a doubly resonant degenerate micro‐optical parametric oscillator (DR‐DμOPO) with the cooperation of χ (2) and χ (3) nonlinearities. Lifting the assumption of close‐to‐zero group velocity mismatch (GVM) that requires extensive dispersion engineering, we show that there is a threshold GVM above which single PD‐DKS in DR‐DμOPO can be generated deterministically. We find that the exact PD‐DKS generation dynamics can be divided into two distinctive regimes depending on the phase matching condition. In both regimes, the perturbative effective third‐order nonlinearity resulting from the cascaded quadratic process is responsible for the soliton annihilation and the deterministic single PD‐DKS generation. We also develop the experimental design guidelines for accessing such deterministic single PD‐DKS state. The working principle can be applied to different material platforms as a competitive ultrashort pulse and broadband frequency comb source architecture at the mid‐infrared spectral range.
