光学谐振腔中原子阵列的量子光

Quantum light by atomic arrays in optical resonators

Hessam Habibian, Stefano Zippilli, Giovanna Morigi

摘要:

研究了原子与高精细光学谐振腔模式耦合并受激光驱动时,原子阵列的光散射。当von-Laue条件不满足时,腔模中没有相干辐射,后者是通过非弹性散射过程泵浦的。我们考虑这种情况,并确定不同的非线性光学过程可能发生的条件。我们表明,这些过程可以通过适当地调整激光和腔耦合的强度,激光和腔轴之间的角度,和阵列的周期性来控制。当系统既可以作为简并参量放大器工作,又可以作为反聚束光源工作时,我们描述了光的相干特性。我们的研究使我们能够识别的原子阵列和相应的参数制度的非线性光学响应的各个多光子组件,从而在原则上允许一个控制介质的非线性光学响应。

英文摘要:

Light scattering by a periodic atomic array is studied when the atoms couple with the mode of a high-finesse optical resonator and are driven by a laser. When the von-Laue condition is not satified, there is no coherent emission into the cavity mode, and the latter is pumped via inelastic scattering processes. We consider this situation and identify conditions for which different non-linear optical processes can occur. We show that these processes can be controlled by suitably tuning the strength of laser and cavity coupling, the angle between laser and cavity axis, and the array periodicity. We characterize the coherence properties of the light when the system can either operate as degenerate parametric amplifier or as a source of antibunched-light. Our study permits us to identify the individual multi-photon components of the nonlinear optical response of the atomic array and the corresponding parameter regimes, thereby in principle allowing one for controlling the nonlinear optical response of the medium.
