Numerical and experimental full synchronization of 2 × 2 optoelectronic device network

Numerically and experimentally the full synchronization of 2 × 2 optoelectronic device network. By the using of 2×2 oscillator’s network, every one of the oscillators has been considered as optocoupler (i.e. LED that has been coupled with photodetector). By fixing the strength of the feedback (E) and increasing the current of the bias (δ) of every one of the oscillators, the dynamic sequence like chaotic and periodic mixed-mode oscillations has been observed. Synchronization of unidirectionally coupled optoelectronic devices network has been featured when bias current equal to 4.4 × 10−4 . Transitions between the synchronization and the non-synchronization states through spatiotemporal distributions have been investigated.
