SPILKING GENERATION AND SYNCHRONIZATION IN SEMICONDUCTOR LASER BY MEANS OF OPTICAL FEEDBACK

Nonlinear dynamics of a semiconductor laser subjected optical feedback observed numerically. The investigation performed based on numerical simulation of Lang-Kobayashi time delay rate equations over wide range of optical feedback strength. The results show that under small, moderate and high optical feedback strength semiconductor laser output power goes different dynamical regimes involving steady state, periodic, mixed modes and chaotic spiking. These dynamics analyzed by time series and their FFt power spectrum with phase space trajectory. The bifurcation diagram is drawn as a function of optical feedback strength. Chaos synchronization in unidirectional coupling scheme numerically presented
