论文摘要
我们通过泵频率扫描通过分析和数值研究了CW泵式谐振的光学参数振荡器中的直接孤子生成。通过对均质溶液的分叉和线性稳定性分析，我们根据泵和信号组速度分散（GVD）区分独特的孤子形成机制和相应的动力学。据我们所知，这是关于纯二次孤子动力学的第一个研究。此外，我们讨论了如何通过调整泵和信号GVD引入调制不稳定性来扩展现有的现有制度并轻松访问二次孤子。我们的研究将使纯二次孤子子的理论腔设计和实验实现受益。
We analytically and numerically study the direct soliton generation in a cw-pumped doubly resonant degenerate optical parametric oscillator via pump frequency scanning. By means of bifurcation and linear stability analysis of the homogeneous solutions, we discriminate distinctive soliton forming mechanisms and corresponding dynamics, depending on pump and signal group velocity dispersions (GVDs). To the best of our knowledge, this is the first study regarding the dynamics of pure quadratic solitons. In addition, we discuss how to extend soliton existing regime and easily access quadratic soliton by introducing modulation instabilities through the adjustment of pump and signal GVDs. Our study will benefit the theoretical cavity design and experimental realization for pure quadratic solitons.
