We model backscatter for electric fields propagating through optical micro-ring resonators, as occurring both in-ring and in-coupler. These provide useful tools for modelling transmission and in-ring fields in these optical devices. We then discuss spontaneous four-wave mixing and use the models to obtain heralding efficiencies and rates. We observe a trade-off between these, which becomes more extreme as the rings become more strongly backscattered.

微环谐振器中的反向散射和自发四波混频

我们对通过光学微环谐振器传播的电场进行反向散射建模，如环内和耦合器中均发生。这些为模拟这些光学设备中的传输和环内场提供了有用的工具。然后我们讨论自发四波混频并使用这些模型来获得预兆效率和速率。我们观察到这些之间的权衡，随着环变得更强烈的反向散射，这种权衡变​​得更加极端。
