带反馈的半导体激光器是研究非线性光学系统混沌动力学的一个很好的模型。它不仅从基础物理研究的角度看是有趣的，而且从应用的角度看也是有趣的。本文综述了反馈诱导的不稳定性和混沌动力学，特别是光反馈诱导的不稳定性和混沌动力学及其应用。这种系统的模型由激光速率方程描述。本文首先从理论和实验两方面讨论了半导体激光器中反馈诱导不稳定性和混沌的动力学行为。通过混沌控制的方法可以使不稳定和混沌稳定。并将此方法应用于抑制半导体激光器中的反馈噪声。两个相似系统之间的混沌同步也是混沌应用中的一个重要问题，我们讨论了基于混沌同步的保密通信。还介绍了反馈诱导混沌的一些应用实例。
Semiconductor laser with feedback is an excellent model for nonlinear optical system which shows chaotic dynamics. It is interesting not only from the fundamental physical study but also application standpoints of view. The dynamics of feedback induced instability and chaos, especially for optical feedback, and their applications are reviewed in this paper. The model of such a system is described by the laser rate equations. At first the dynamic behaviors of feedback induced instability and chaos in semiconductor lasers are discussed on the basis of the theory and experiments. Instability and chaos may be stabilized by the method of chaos control. Then we apply the method to suppress the noise induced by the feedback in a semiconductor laser. The synchronization of chaos between two similar systems is also an important issue in chaos applications and we discuss secure communications based on chaos synchronization . Some other examples of applications of feedback induced chaos are also described.
