我们提出了一个超越平均场的方法来预测有机极化激元激光的性质，占所有相关的光子模式在一个平面微腔。从微观图像开始，我们展示了激光如何在与最大增益共振的极化激元态和极化激元色散底部的极化激元态之间切换。我们展示了如何人口的非激射模式可以找到，并通过使用两个时间的相关性，我们展示了光致发光光谱（激射和非激射模式）的泵浦和耦合强度的演变，确认最近的实验工作的起源极化激元激光蓝移。
We present a beyond-mean-field approach to predict the nature of organic polariton lasing, accounting for all relevant photon modes in a planar microcavity. Starting from a microscopic picture, we show how lasing can switch between polaritonic states resonant with the maximal gain, and those at the bottom of the polariton dispersion. We show how the population of nonlasing modes can be found, and by using two-time correlations, we show how the photoluminescence spectrum (of both lasing and nonlasing modes) evolves with pumping and coupling strength, confirming recent experimental work on the origin of blueshift for polariton lasing.
