摘　　要：给出了双区半导体激光器产生混沌的条件,研究了双区半导体激光器的混沌及其同步,利用混沌驱动法和连续变量反馈法实现了激光器的混沌同步,通过计算最大条件Lyapunov指数随注入强度及反馈权重的变化,得到了可以达到混沌同步的注入参数及反馈权重的取值范围,最后又对两种方法进行了对比分析。The chaos and chaotic synchronization of two-section semiconductor laser have been investigated. The condition of the chaos of two-section semiconductor laser has been presented ; we realize the synchronization of chaos using the chaotic driving method and the successive variable feedback method, also we find the parameter＇ s area for chaotic synchronization through calculating the relationship between the maximum conditional Lyapunov exponents and the driving intensity or the feedback coefficient. Then we make analyses between the two methods.
