摘　　要：提出了带有光延迟反馈回路的单环掺铒光纤激光器系统,并对其动力学特性进行了分析。在传输信息幅度较小时,利用信息掩盖技术在掺铒光纤激光器系统中实现了混沌的保密通信,即使系统的参数在一定范围内存在失配时,混沌同步也可以维持得非常好。An erbium-doped fiber single-ring laser system with optical delay feedback is proposed,and the nonlinear dynamics is analyzed.The chaotic secure communication in erbium-doped fiber laser systems for the scheme of message-masking is investigated numerically with small amplitude of transmitted signal.Numerical simulation shows that the synchronization is maintained quite well with mismatches of parameters among an appropriate range.
