利用非线性耦合模方程，数值研究了正常色散微腔系统中克尔梳的产生，其中两个腔模之间存在模式耦合。与以往的研究相比，我们的模型是严格的，我们充分考虑了两个模式之间的模式耦合。我们研究的相位匹配条件，以获得所需的合适的参数，形成一个自由光谱范围（FSR）可选的梳。我们的计算是在良好的协议与现有的实验结果，使我们能够获得很好的理解的现象，而且我们的模型也使我们能够揭示新的现象。我们详细研究了1-FSR梳状波的产生，发现当失谐量扫描时，会出现随机振荡行为，这是以前从未观察到的。这种建模方法将是一个强大的工具，将有助于色散工程克尔梳的产生和频率调谐需要产生一个确定性的锁模梳。
By using nonlinear coupled mode equations, we numerically investigated the generation of a Kerr comb in a normal dispersion microcavity system, where mode coupling between two cavity modes is present. In contrast to previous studies, our model is rigorous in which we fully considered the mode coupling between two modes. We investigated the phase matching condition to obtain the suitable parameters needed to form a free-spectral-range (FSR)-selectable comb. Our calculations are in good agreement with existing experimental results, and enable us to obtain a good understanding of the phenomenon; moreover our model also allows us to reveal new phenomena. We investigated 1-FSR comb generation in detail and found that randomly oscillating behavior will appear when detuning is scanned, which has never before been clearly observed. This modeling approach will be a powerful tool that will assist dispersion engineering for Kerr comb generation and the frequency tuning needed to generate a deterministic mode-locked comb.
