We perform the first theoretical modeling of the full spectral-temporal dynamics of octave-spanning parametric microresonator comb generation through use of the Lugiato-Lefever model extended to include higher-order dispersion and self-steepening. We show that three distinct stages are necessary to achieve single-pulse modelocking and discuss the dispersion characteristics required for ultrabroadband, stabilized comb generation. Our simulations agree well with previous experimental demonstrations and predict many of the observed features, including multipulse generation, dispersive wave generation, modelocking, and comb stabilization.
我们通过使用扩展到包括高阶色散和自陡峭的 Luigiato-Lefever 模型，对跨越倍频程的参量微谐振器梳状产生的全谱-时域动态进行了首次理论建模。我们表明，实现单脉冲锁模需要三个不同的阶段，并讨论了超宽带、稳定梳状产生所需的色散特性。我们的模拟与先前的实验演示吻合得很好，并预测了许多观察到的特征，包括多脉冲产生、弥散波产生、锁模和梳状稳定。
