New resonant emission of dispersive waves by oscillating solitary structures in optical fiber cavities is considered analytically and numerically. The pulse propagation is described in the framework of the Lugiato-Lefever equation when a Hopf-bifurcation can result in the formation of oscillating dissipative solitons. The resonance condition for the radiation of the dissipative oscillating solitons is derived and it is demonstrated that the predicted resonances match the spectral lines observed in numerical simulations perfectly. The complex recoil of the radiation on the soliton dynamics is discussed. The reported effect can have importance for the generation of frequency combs in nonlinear microring resonators.
通过光纤腔中的振荡孤子结构产生的色散波新共振发射，进行了理论和数值分析。当霍普夫分岔可导致振荡耗散孤子形成时，在Lugiato-Lefever方程框架内描述脉冲传播。推导了耗散振荡孤子辐射的共振条件，并证明预测的共振与数值模拟中观察到的光谱线完美匹配。讨论了辐射对孤子动力学的复杂反冲。所报道的效应对于非线性微环谐振器中频率梳的产生可能具有重要意义。
