Instabilities and Chaos in Semiconductor LaserWith Optical Injection and Feedback


A numerical has been under taken to study the effects of the optical injection and the optical feedback on the nonlinear dynamical behavior of the semiconductor laser using a simple model, based on the coupled electric field and population inversion rate equations. A number of distinct states are obtained. These include periodic limit – cycle operation , quasiperiodicity, and chaotic behaviors dependent on the type of the laser control parameter and the operating conditions.
