Abstract :

The investigation of the existence of chaotic spiking in the dynamics of a semiconductor laser with an optical feedback was demonstrated theoretically by laser rate equations that describe the temporal variation of photon density and carrier density. The influence of changing the bias current on nonlinear dynamic are studied and the bifurcation diagram is achieved as a function of this parameter. Chaos synchronization between two distinct chaotic systems with independent initial conditions when add a common bias current is also considered.
