半导体微腔中环形极化激元参量发光的量子蒙特卡罗研究

Quantum Monte Carlo study of ring-shaped polariton parametric luminescence in a semiconductor microcavity

摘要:

本文用量子蒙特卡罗方法研究了半导体微腔强激子-光子耦合参量发光中的量子关联。如在最近的实验中已经证明的,通过应用具有相反的面内波矢量的两个相同的泵浦光束,在环上提供具有相反的面内波矢量的对称信号和空闲光束,来获得环形发射。我们研究了信号-闲频差噪声在参量不稳定性阈值上的压缩,考虑了辐射和非辐射损失、多重散射和静态无序。我们比较了完整的多模蒙特卡罗模拟与简化的线性化量子朗之万分析模型的结果。

英文摘要:

We present a quantum Monte Carlo study of the quantum correlations in the parametric luminescence from semiconductor microcavities in the strong exciton-photon coupling regime. As already demonstrated in recent experiments, a ring-shaped emission is obtained by applying two identical pump beams with opposite in-plane wavevectors, providing symmetrical signal and idler beams with opposite in-plane wavevectors on the ring. We study the squeezing of the signal-idler difference noise across the parametric instability threshold, accounting for the radiative and non-radiative losses, multiple scattering and static disorder. We compare the results of the complete multimode Monte Carlo simulations with a simplified linearized quantum Langevin analytical model.
