The work demonstrates a systematic investigation on a microcavity-feedback fiber-loop laser, from the coupling between the waveguide and WGM microavity, to the studies of lasing characterisitcs based on the rate equation models. Previous works are mainly focused on the waveguding optics of WGM microcavity, here, we consider the laser as a system and two critical coupling states are given and a new method to evaluate the linewdith of WGM is proposed.

用速率方程模型研究微腔反馈光纤环激光器


这项工作展示了对微腔反馈光纤环路激光器的系统研究，从波导和 WGM 微腔之间的耦合，到基于速率方程模型的激光特性研究。以往的工作主要集中在WGM微腔的波导光学器件上，这里，我们将激光器视为一个系统，给出了两个临界耦合态，并提出了一种评估WGM线宽的新方法。
