论文摘要
已知驱动的高Q Si微腔表现出源自载体诱导的和热光线非线性的极限周期振荡。我们提出了一种新型的纳米光子装置，以实现与耦合硅（SI）光子晶体（PHC）微腔的同步光限期振荡。在这里，使用相干耦合的SI PHC微腔来实现耦合极限循环振荡器。通过模拟耦合模式方程，我们从理论上证明了通过相干耦合诱导的两个极限循环的相互同步（夹带）。此外，我们在相描述框架中解释了数值模拟的同步。由于我们提出的设计与当前的硅光子制造过程完全兼容，因此将在未来的硅光子电路中实现光学极限循环振荡的同步。
A driven high-Q Si microcavity is known to exhibit limit cycle oscillation originating from carrier-induced and thermo-optic nonlinearities. We propose a novel nanophotonic device to realize synchronized optical limit cycle oscillations with coupled silicon (Si) photonic crystal (PhC) microcavities. Here, coupled limit cycle oscillators are realized by using coherently coupled Si PhC microcavities. By simulating coupled-mode equations, we theoretically demonstrate mutual synchronization (entrainment) of two limit cycles induced by coherent coupling. Furthermore, we interpret the numerically simulated synchronization in the framework of phase description. Since our proposed design is perfectly compatible with current silicon photonics fabrication processes, the synchronization of optical limit cycle oscillations will be implemented in future silicon photonic circuits.
