Abstract

A periodic control method by external optical injection strength in the semiconductor laser is presented. The numerical simulation results show that when the injection strength is periodic controlled at the time of 10ns, chaotic state will be controlled into periodic state at the appropriate optical injection coefficient, such as single-periodic state, dual-periodic state and three-periodic state et al.. With the optical injection coefficient increases, the modulation frequency will increase. The method can control the chaos to less periodic and more stable state, it’s meaningful to improve the efficiency of the laser output and inhibit the generation of chaos..
