研究了拉曼散射和高阶色散对硅微环谐振腔中孤子和频率梳产生的影响。拉曼效应在谐振腔品质因数中引入了一个阈值，高于这个阈值的锁频孤子不可能存在，相反，观察到了以产生自频移孤子和色散波为特征的丰富的动力学。还报道了通过锁频孤子的Hopf不稳定性来展宽切伦科夫辐射的机制。
The influence of Raman scattering and higher order dispersions on solitons and frequency comb generation in silica microring resonators is investigated. The Raman effect introduces a threshold value in the resonator quality factor above which the frequency-locked solitons cannot exist, and instead, a rich dynamics characterized by generation of self-frequency-shifting solitons and dispersive waves is observed. A mechanism for broadening the Cherenkov radiation through Hopf instability of the frequency-locked solitons is also reported.
