摘　　要：根据双环掺铒光纤激光器互耦合的结构特点,提出利用互注入对其混沌进行控制的方法。基于互注入双环掺铒光纤激光器的理论模型,模拟了激光器的动态特性。通过适当的调节互注入强度和延迟时间,可以同时把两个双环掺铒光纤激光器从混沌态控制到多周期态,周期1或2,以及稳态,实现了两个光纤激光器混沌行为的动态的相互控制。在此模型基础上附加反馈,实现了二者的混沌同步,并定量的分析了互注入强度和延迟时间,以及参数失配对同步性能的影响。According to the mutual-coupling structural property of dual-ring erbium-doped fiber lasers, a scheme of controlling chaos with mutual injection is presented. Based on the theoretical model of mutually injected dual-ring erbium-doped fiber lasers, the dynamic characteristics of the lasers are simulated. By adjusting properly the mutual injection strength and delay time, the two dual-ring erbium-doped fiber lasers can be simultaneously controlled into multi- period, period 1 or 2, and steady states. Therefore, mutual control of chaotic dynamics in a couple of fiber lasers could be realized dynamically. It is also found that the output of the two lasers can exhibit chaotic synchronization when feedback is added to this model. The influence of the mutual injection strength, delay time, and the parameter mismatch between the two lasers on the quality of synchronization are quantitatively analyzed.
