基于光电负反馈的激光混沌串联同步系统研究

Investigation on the cascade synchronization system based on the optoelectronic negative feedback chaotic lasers

提出了一种新的混沌中继系统,该系统基于光电负反馈的激光混沌串联同步.对该系统的同步性以及激光器内部参数失配对其同步性的影响进行了研究,并与基于光反馈的激光混沌串联同步系统进行了比较.研究结果表明:当系统参量满足一定条件时,该系统能实现完全同步;当激光器内部参数失配时,其混沌同步性会受到一定的影响,但该系统的混沌同步性对参数失配的容忍性要比基于光反馈的系统好得多.

A novel chaotic repeater system based on the cascade synchronization in optoelectronic negative feedback chaotic lasers is proposed.The synchronization characteristics and the influence of the parameter mismatch on the synchronization have been investigated.The results show that complete synchronization can be realized with suitable system parameters,and the internal parameter mismatch of the lasers have influence on the synchronization quality.But the system has greater robustness to parameter mismatch compared with the cascade synchronization based on the optical feedback.
