| 摘 要： | 对外部光反馈结构的F_P半导体激光器模型进行了理论分析,根据微小信号理论,导出了激光器的一阶近似扰动方程,由此可判别激光器输出工作状态。改变外部光反馈结构半导体激光器的一些典型参数,并测试它们对激光器输出的影响。通过参数选择可以控制激光器输出工作在混沌状态,从而实现混沌保密通信应用的基本条件。

| Abstract: | The F_P semiconductor laser subjected to external optical feedback is analyzed theoretically. According to the theory of small signal,first-order approximation of perturbation equation of a laser is derived;as such, the operating state of the semiconductor laser can be discriminated.The influences of some parameters on the output of a laser are tested by adjusting their values.By choosing appropriate values for the parameters,the lasers can be controlled to operate in chaos state,thereby,the application of ... |
