Abstract

我们理论上调查由一种类型的单个光子的散布三水平的系统与被完整的量机械的途径联合到一个维的波导的一个 whispering-gallery-type 共鸣器交往。单个光子的传播振幅和思考振幅完全经由真实空间的途径被获得。由经典的光地控制的单个光子的运输性质被讨论。在有三水平的系统的联合 waveguide-whispering-gallery 共鸣器原子的批评联合条件也被分析。

We analyze the single-photon transport in a single-mode waveguide coupled to a whispering-gallery-type resonator interacting with a two-level atom. The single-photon transport properties such as the transmission and reflection amplitudes, as well as the resonator and the atom responses, are solved exactly via a real-space approach. The treatment includes the intermode backscattering between the two degenerate whispering-gallery modes of the resonator, and the dissipations of the resonator and the atom. We also show that a generalized critical coupling condition, that the single-photon transmission at the output of the waveguide goes to zero on resonance for a matched system, holds for the full coupled waveguide-ring resonator-atom system.
