Abstract

An optical secure communication system based on digital chaos and Polarization Shift Keying (PolSK) technology is proposed. In several selected PolSK schemes, states of polarization are partially or totally uniform on Poincare sphere. Different PolSK schemes are chosen according to the real-time chaos-based pseudo-random sequences to modulate original information in different periods of clock of the transmitter. In the receiver, according to the synchronous chaotic sequences, corresponding PolSK schemes are used to demodulate the information. Simulation is carried out by using the softwares of OptiSystem and Matlab. Some analysis results are presented. In the conclusion, this system works well in communication and has strong anti-attack capacity.
