摘　　要：基于双区半导体激光器的速率方程,研究了双区半导体激光器的超混沌现象,给出了双区半导体激光器产生超混沌的条件;利用驱动-响应法实现了双区半导体激光器的超混沌同步,通过计算激光系统最大条件李亚谱诺夫指数随注入强度的变化,得到实现超混沌同步的注入参量的取值范围。Based on the rate equations, the hyperchaos of two-section semiconductor laser has been studied and the condition.of hyperchaos has been presented. We realize the synchronization of chaos using the chaotic driving method, and also find the parameter＇s range for hyperchaotic synchronization through calculating the relationship between the maximum conditional Lyapunov exponents and the driving intensity.
