论文摘要
从理论上讲，我们在\ c {hi}（hi}（2）和\ c {hi}（hi}（hi}（3）非线性的合作）中，我们在双重谐振的简化微分光振荡振荡器（DR-DμOPO）中研究了参数驱动的耗散性Kerr Soliton（PD-DKS）的性质。提升需要广泛的分散工程的近距离速度速度不匹配（GVM）的假设，我们表明存在一个阈值GVM，可以确定性地生成DR-DμOPO中的单个PD-DKS。我们发现，根据相位匹配条件，确切的PD-DKS生成动力学可以分为两个独特的机制。在这两个制度中，由级联的二次过程产生的扰动有效的三阶非线性是孤子歼灭和确定性的单个PD-DKS生成的原因。我们还制定了用于访问此类确定性单个PD-DKS状态的实验设计指南。可以将工作原理应用于不同的材料平台，作为中型光谱范围内的竞争性超短脉冲和宽带频率梳子源体系结构。
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 \c{hi}(2) and \c{hi}(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.
