Controlling two chaotic lasers via OD-DCF

We present a novelty optoelectronic delay double-cross-feedback (OD-DCF) scheme to control two chaotic lasers based on coupled lasers. design out the OD-DCF technical solution convert lights from into photocurrents by photo-detectors, and then are cross-fed back each other’s respectively suppress oscillations guide laser’s dynamics behaviours, respectively. By adjusting feedback levels delayed time of OD-DCF, can obtain chaos-control show all kinds behaviours. find that oscillation behaviours suppressed stable state different quasi-cycle states, such as cycle-one, cycle-two, cycle-three, cycle-four, other states. also movement be controlled lead cycle-double The results prove effectively realized via OD-DCF. It is very helpful for our studies science, nonlinear optics, chaos, laser.
