Chaos synchronization delay in semiconductor lasers with optoelectronic feedback

Abstract

In this work we reported the synchronization delay in semiconductor laser (SL) networks. The unidirectional configurations between successive oscillators and the correlation between them are achieved. The coupling strength is a control parameter so when we increase coupling strength the dynamic of the system has been change. In addition the time required to synchronize network components (delay of synchronization) has been studied as well. The synchronization delay has been increased by mean of increasing the number of oscillators. Finally, explanation of the time required to synchronize oscillators in the network at different coupling strengths.
