We study the scattering problem of photon and polariton in a one-dimensional coupled-cavity system. Analytical approximate analysis and numerical simulation show that a photon can stimulate the photon emission from a polariton through polariton-photon collisions. This observation opens the possibility of photon-stimulated transition from insulating to radiative phase in a coupled-cavity QED system. Inversely, we also find that a polariton can be generated by a two-photon Raman scattering process. This paves the way towards single photon storage by the aid of atom-cavity interaction.
我们研究了一维耦合腔系统中光子与极化激元的散射问题。解析近似分析和数值模拟表明,光子可以通过极化激元 - 光子碰撞激发极化激元的光子发射。这一发现为耦合腔量子电动力学系统中从绝缘相到辐射相的光子激发跃迁开辟了可能性。相反,我们还发现极化激元可以通过双光子拉曼散射过程产生。这为借助原子 - 腔相互作用实现单光子存储铺平了道路。
