Investigation on the cascade synchronization system based on the optoelectronic negative feedback chaotic lasers
基于光电负反馈的激光混沌串联同步系统研究

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.
