摘　　要：分析了掺铒光纤环形激光器中非线性高频混沌产生和同步的基本原理.提出了高频波长可调谐光混沌产生的实验方案,实验实现了不同波长高频混沌的产生.实验获得了高频混沌在传输1km后与接收机激光器产生混沌的同步,为构建高速动态保密光混沌通信网络扫清障碍.Fundamental principles of high-frequency chaos generation and synchronization in Er-doped fiber ring lasers are analyzed. The experimental configuration for generating wavelength-tunable chaos is proposed, and high-frequency chaotic lasers at different wavelengths are generated. Synchronization between the chaos generated in the receiver laser and the chaos transmitted over 1 km that is generated in the transmitter laser are achieved, which paves the way for constructing the high speed secure chaos communication network.
