We introduce a technique for controlling cavity QED by indirectly coupling two planar-photonic-crystal nanocavities through an integrated waveguide. Guided by an explicit analytical expression for the photon Green function, the resulting optical response of a single quantum dot, embedded in one of the cavities, is shown to be profoundly influenced by the distant cavity. The regimes of cavity QED, e.g., vacuum Rabi splitting, are made significantly easier and richer than with one cavity alone.
我们介绍了一种通过集成波导间接耦合两个平面光子晶体纳米腔来控制腔量子电动力学的技术。在光子格林函数的显式解析表达式的指导下，嵌入其中一个腔中的单个量子点产生的光学响应被证明受到远处腔的深刻影响。与仅使用一个腔相比，腔量子电动力学的各种机制，例如真空拉比分裂，变得明显更容易实现且更加丰富。
