Abstract
In a light-emitting diode (LED) with ac-coupled nonlinear optoelectronic feedback, chaos can occur within a wide range of the voltage threshold parameter. When two identical such LEDs are coupled without delays, with increase of the coupling strength, transitions occur from anti-phase synchronization of periodic spiking to complete synchronization of chaos. Here we present that a coupling time-delay enhances chaos synchronization with small coupling strengths. The numerical simulations with bifurcation diagrams demonstrate the underlying mechanisms.
