A novel nonlinear chaos-control method of a semiconductor laser is presented by adding a control path of photoelectric delayed nonlinear feedback. Chaos-control physical models of an injected semiconductor laser are studied by using photoelectric nonlinear and linear delayed controllers. And chaos-control equations are analyzed. A route to a periodic state or a cycle-one from chaos is found. Chaos-control...
A round-coupling configuration of two inverse-injection semiconductor lasers is presented for logic gate applications. Two laser diodes coupled via injection from the opposite laser became chaotic. Chaotic synchronization is achieved between the two lasers. Two all-optical or two optoelectronic logic gates can be implemented by modulating the injected light or laser diode current, respectively, to...
Chaotic synchronization of injected multiple-quantum-well lasers of optical fiber system and a theoretical model of optical fiber chaotic secure communication system are presented by coupling a chaotic multiple-quantum-well laser synchronization system and a fiber channel. A new chaotic encoding method of chaos phase shift keying On/Off is proposed for optical fiber secure communications. Chaotic...
