The Theory and System of Alternate Variable Parameters of Chaotic Laser Parallel Synchronization

This paper presents an alternate variable parameter chaos laser parallel synchronization system. The system is composed of two space-coupled different physical structure lasers, including two chaotic laser transmitters showing alternate variable orbits (AVOs) in the phase space via using an alternate variable parameters (A VPs) method, parallel synchronizing with the other two lasers as two receivers. This paper describes the optical A VP path and the AVO signal control component of the system in detail. Therefore, the paper establishes the chaotic AVO parallel synchronization equation and gives a prediction theory of chaotic AVO synchronization while the theory of AVO parallel synchronization is presented. A chaotic AVO parallel synchronization is realized using the AVP method in our numerical simulation. Therefore, our work will be very important and significant for the chaotic synchronization scheme application to enhance the system's security or laser local area synchronization network.
