Abstract

We have demonstrated and characterized the generation of various period states in an optical pulse-injected semiconductor laser. We numerically reveal the rich dynamics of chaos and its control in semiconductor lasers based on the optical-pulse injection. The results show that the semiconductor laser exhibits the rich period states by a method of changing the frequency of optical-pulse under different injected parameters, the laser can be controlled into single-periodic, dual-periodic, triple-periodic, four-periodic, multi-periodic and even chaos respectively. The results also provide what we believe to be a new method to generate various period states in the chaos system..
