First, output dynamics of erbium-doped fiber ring lasers of the sinusoidal loss modulation model was analyzed. By setting the pumping power and the modulation coefficient in the laser as variables, the chaotic output appears with a high pumping power, but disappears under no modulation and the extremely high modulation coefficient condition.Second, synchronization characteristics for the master-slave and slave-slave system was analyzed by using the correlation coefficient between the two laser outputs. In the master-slave type the highest correlation coefficient is obtained with the modulation index of the master subsystem higher than the that of the slave subsystem and with the pumping power of the master subsystem smaller than that of the slave subsystem. In addition, the synchronization characteristics depends dominantly on the pumping power. A similar synchronization characteristics were obtained in the slave-slave system.Finally, dependence of the decoding characteristics of the message on the parameter difference between the two subsystems is analyzed under the message modulation type secure communication system. The error factor of the decoded message is almost proportional to the difference of the pumping power and becomes small with increasing the modulation index.

首先，分析了正弦损耗调制模型下环形腔掺铒光纤激光器的输出动力学特性。以泵浦功率和激光器调制系数为变量，在较高的泵浦功率下出现混沌输出，而在无调制和极高调制系数条件下混沌输出消失。其次，利用两个激光器输出之间的相关系数分析了主从和从从系统的同步特性。在主从型中，当主子系统的调制指数大于从子系统的调制指数，且主子系统的泵浦功率小于从子系统的泵浦功率时，相关系数最大。此外，同步特性主要取决于泵浦功率。最后，在消息调制型保密通信系统中，分析了两个子系统的参数差异对消息解码特性的影响。解码信息的误差因子几乎与泵浦功率差成正比，并且随着调制指数的增大而减小。
