我们提出了一种基于非线性微腔谐振器的OPO结构。这种方法依赖于一个自锁方案，使OPO发射，而不需要热锁定的泵激光器的微腔谐振。通过利用CMOS兼容的微波谐振器，我们实现了振荡的特点是完全没有“关闭”，即自终止行为，这是一个非常常见的和有害的发生在外部泵浦OPO。此外，我们的方案始终产生非常宽的带宽（> 300 nm，受我们的实验设置的限制）的梳，振荡的间距等于微腔谐振的FSR。
We report a novel geometry for OPOs based on nonlinear microcavity resonators. This approach relies on a self-locked scheme that enables OPO emission without the need for thermal locking of the pump laser to the microcavity resonance. By exploiting a CMOS-compatible microring resonator, we achieve oscillation featured by a complete absence of "shutting down", i.e. the self-terminating behavior that is a very common and detrimental occurrence in externally pumped OPOs. Further, our scheme consistently produces very wide bandwidth (>300nm, limited by our experimental set-up) combs that oscillate at a spacing equal to the FSR of the micro cavity resonance.
