Chaoticlaser Networks

Abstract: We report on chaotic spiking and its synchronization in semiconductor lasers with optical feedback. The effects of the bias current, optical feedback strength and external noise are first studied on the single system by means of bifurcation diagrams. Chaos synchronization is then considered in network of 256 distinct chaotic systems with independent initial conditions when a common Gaussian noise is added. The transition between non synchronization to synchronization states by means of a suitable spatio-temporal representation has been reported.
