Abstract

We analyze the turn-on delay of quantum cascade lasers (QCLs) under pumping with a trapezoidal current pulse. The simulation is based on a system of rate equations for a three-level laser system. We identify five QCL regimes, for which appropriate analytical formulas for the turn-on delay estimation are obtained. The analytical results are in good qualitative agreement with numerical simulations. It is shown that the turn-on delay depends nonlinearly on the rise time of the pump-pulse leading edge.

梯形电流脉冲泵浦下量子级联激光器的开启延迟分析

分析了梯形脉冲泵浦作用下量子级联激光器的导通延时。仿真是基于一个三能级激光系统的速率方程系统。我们确定了5个QCL区域，并给出了相应的导通延迟估计的解析公式。分析结果与数值模拟结果定性一致。结果表明，导通延时与泵脉冲前缘的上升时间呈非线性关系。
