An external mirror coupling to a cavity with a two-level atom inside is put forward to control the photon transport along a one-dimensional waveguide. Using a full quantum theory of photon transport in real space, it is shown that the Rabi splittings of the photonic transmission spectra can be controlled by the cavity-mirror couplings; the splittings could still be observed even when the cavity-atom system works in the weak coupling regime, and the transmission probability of the resonant photon can be modulated from 0 to 100%. Additionally, our numerical results show that the appearance of Fano resonance is related to the strengths of the cavity-mirror coupling and the dissipations of the system. An experimental demonstration of the proposal with the current photonic crystal waveguide technique is suggested.
提出了一种外部镜子与内部有二能级原子的腔耦合的方案，以控制光子沿一维波导的传输。利用实空间中光子传输的全量子理论表明，光子透射谱的拉比分裂可以通过腔镜耦合来控制；即使腔 - 原子系统工作在弱耦合 regime 时，分裂仍然可以被观察到，并且共振光子的传输概率可以从 0 调制到 100%。此外，我们的数值结果表明，法诺共振的出现与腔镜耦合强度和系统的耗散有关。建议利用当前的光子晶体波导技术对该方案进行实验演示。
