Polariton-photon transition in coupled-cavity QED system
C. Li, Z. Song · arXiv (Cornell University) · 2015
We study the scattering problem of photon and polariton in 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 for the amplification photons, i.e., a field radiation can stimulate the transition from insulating to radiative phase of a coupled-cavity QED system. We also find that a single-photon transmission through a quantum switch is affected significantly by a polariton at the switch. Inversely, a polariton can be generated by two colliding single photons by the aid of atom-cavity interaction.
