Noise Effects on Generalized Chaos Synchronization in Semiconductor Lasers

We investigate the effects of noise in drive and/or response systems on generalized synchronization. We show numerically that noise in a drive system can induce synchronization in an unidirectionally coupled Lorenz system, while noise in a response system disrupts the synchronization. In addition, through experiments using coupled semiconductor lasers with optical feedback, we observe that nois...

Chaos synchronization based on a continuous chaos control method in semiconductor lasers with optical feedback.

Chaos synchronization using a continuous chaos control method was studied in two identical chaotic laser systems consisting of semiconductor lasers and optical feedback from an external mirror. Numerical calculations for rate equations indicate that the stability of chaos synchronization depends significantly on the external mirror position. We performed a linear stability analysis for the rate...

Chaos Synchronization in Semiconductor Lasers With Optoelectronic Feedback

Chaos synchronization is experimentally investigated in semiconductor lasers with delayed optoelectronic feedback. Depending on the coupling strength of the driving signal to the receiver, the lasers fall into different regimes of chaos synchronization or modulation. Synchronization happens when the coupling strength to the receiver matches the feedback strength to the transmitter, where the re...
