摘要

来自外腔的光反馈可以迫使半导体激光器以非常窄的线宽在单模中振荡。然而，超过一定的临界反馈水平，激光可能切换到一个看似混沌的状态，其中线宽增加了几个数量级。我们通过计算机模拟复电场β(t) exp(jωot)和载流子密度N(t)的耦合速率方程，对这一转变进行了理论研究。

Nonlinear Dynamics for a Semiconductor Laser with Optical Feedback

The optical feedback from an external cavity may force a semiconductor laser to oscillate in a single mode with very narrow linewidth. However, above a certain critical level of feedback the laser may switch to a seemingly chaotic state in which the linewidth is increased by several orders of magnitude. We report on a theoretical study of this transition by computer simulation of the coupled rate equations for the complex electric field β(t) exp(jωot) and the carrier density N(t).
