一维波导中三能级发射体的光子散射

Photon scattering by a three-level emitter in a one-dimensional waveguide

D. Witthaut, A. S. Sorensen

摘要:

讨论了一维波导中三能级发射体对光子的散射,其中光子的输运受自发发射波和直接透射波的干涉控制。对于不同层次的结构,散射问题以封闭形式求解。几种可能的应用进行了讨论:发射器的状态可以确定性地切换拉曼散射,从而使应用在量子计算,如单光子晶体管。发射器阵列产生光子带隙结构,其可以由经典驱动激光器调谐。无序排列导致光子的安德森局域化,其中局域化长度可以再次由外部驱动控制。

英文摘要:

We discuss the scattering of photons from a three-level emitter in a one-dimensional waveguide, where the transport is governed by the interference of spontaneously emitted and directly transmitted waves. The scattering problem is solved in closed form for different level structures. Several possible applications are discussed: The state of the emitter can be switched deterministically by Raman scattering, thus enabling applications in quantum computing such as a single photon transistor. An array of emitters gives rise to a photonic band gap structure, which can be tuned by a classical driving laser. A disordered array leads to Anderson localization of photons, where the localization length can again be controlled by an external driving.
