Abstract

The polariton dynamics in a microcavity in the parametric oscillator mode is studied when two pump polaritons turn into polaritons of signal and idler modes and vice versa. The pumping is performed by two laser pulses with close frequencies. Analytical solutions to a system of nonlinear differential equations are obtained. Periodic and aperiodic regimes of transformation of a pair of pump polaritons into polaritons of signal and idler modes, as well as the quiescent mode of the system, are obtained.

半导体微腔中激子-极化子参量振荡的非线性动力学

摘要

当两个泵浦极化子变成信号和惰轮模式的极化子，反之亦然时，研究了在参数振荡器模式下微腔中的极化子动力学。泵浦由两个频率接近的激光脉冲执行。获得了非线性微分方程系统的解析解。获得了将一对泵浦极化子转变为信号和惰轮极化子以及系统静态模式的周期性和非周期性状态。
