我们提出了一种基于三个光学共振的选择性耦合实现热双稳态的方案。这种方法要求其中一个谐振频率与温度相关，这可能发生在表现出强烈热光效应的材料中。为了说明，我们探讨热双稳态在两个不同的无源系统，涉及到一个周期性阵列的硅环谐振器或平行GaAs薄膜分离真空和交换热在近场。这样的方案可以被证明是有用的热设备操作的过渡时间在数百毫秒的顺序。
We present a scheme for achieving thermal bistability based on the selective coupling of three optical resonances. This approach requires one of the resonant frequencies to be temperature dependent, which can occur in materials exhibiting strong thermo-optic effects. For illustration, we explore thermal bistability in two different passive systems, involving either a periodic array of Si ring resonators or parallel GaAs thin films separated by vacuum and exchanging heat in the near field. Such a scheme could prove to be useful for thermal devices operating with transition times on the order of hundreds of milliseconds.
