We demonstrate that extended dissipative structures in Kerr-nonlinear whispering-gallery mode resonators undergo a spatiotemporal instability, as the pumping parameters are varied. We show that the dynamics of the patterns beyond this bifurcation yield specific Kerr comb and sub-comb spectra that can be subjected to a phase of frequency-locking when optimal conditions are met. Our numerical results are found to be in agreement with experimental measurements.
我们证明,随着泵浦参数的变化,克尔非线性回音壁模式谐振器中的扩展耗散结构会经历时空不稳定性。我们表明,在此分岔之外的图案动力学产生特定的克尔频率梳和子频率梳光谱,当满足最佳条件时,这些光谱会进入锁相阶段。我们的数值结果与实验测量结果一致。
