Studies on chaotic multiple-quantum-well laser synchronization via controlling phase and its application in secure communication using external chaos phase shift keying modulation

In this paper, the control of chaotic external injection multiple quantum well laser synchronization via phase controllers is presented and external chaos phase shift keying modulation is proposed for secure communication. Chaotic laser synchronization is numerically achieved under controlling by phase controllers. Lasing phase shift is controlled via continuous ON/ON chaos shift keying and chaotic laser signal is transmitted by chaos phase shift keying modulation on end. Chaotic laser demodulation is realized by setting a phase shift of the receiver phase controllers. ON/ON chaos phase shift keying communications at bit rates of 0 1 and 0 5Gbit/s are numerically simulated. ON/ON chaos phase shift keying communication bit rate,the synchronization characterization and the system parameter mismatch are numerically analyzed, in particular.
