We show that a pair of quantized modes interacting with a spectrally broadened ensemble of Lambda-type atoms is analogous to an ensemble of two-level systems coupled to a bosonic reservoir. This enables an irreversible photon transfer between photon modes. The reservoir can be engineered which allows the observation of effects such as the Zeno and anti-Zeno effect, the destructive interference of decay channels, and the decay in a squeezed vacuum. We also consider a photon diode, i.e., a device which directs a single photon from any one of two input ports to a common output port.
我们表明，与光谱展宽的Lambda 型原子系综相互作用的一对量子化模式类似于与玻色子库耦合的两个能级系统的系综。这使得光子模式之间能够发生不可逆的光子转移。该库可以进行工程设计，从而可以观察到诸如芝诺和反芝诺效应、衰减通道的相消干涉以及在压缩真空中的衰减等现象。我们还考虑了一种光子二极管，即一种能够将单个光子从两个输入端口中的任意一个引导到公共输出端口的器件。
