Abstract

We numerically investigate the effects of coupling delays on the synchronization dynamics of two coupled chaotic light-emitting diodes (LEDs) with ac-coupled nonlinear optoelectronic feedback. With zero-lag or very small time-delay coupling, as the coupling strength increases, the coupled system exhibits weak anti-phase multi-spike synchronization, strong anti-phase low-frequency spike synchronization and finally complete chaos synchronization. With a coupling delay large enough, not only the chaotic spiking is eliminated, but also new high amplitude high frequency regular spike synchronization of coupled LEDs can be obtained.
