本文提出了一种基于变量与周期信号耦合的弱周期微扰法控制双环掺铒光纤激光器混沌的具体方案。数值模拟结果表明,通过适当调节反馈强度,该方法可实现对双环掺铒光纤激光器混沌和超混沌的控制。
In this paper, a scheme based on the weak periodic perturbation method coupled with variable signal and periodic signal to control the chaos of double-ring erbium-doped fiber laser is proposed. The numerical simulation results show that this method can control the chaos and hyperchaos of the double-ring erbium-doped fiber laser by properly adjusting the feedback intensity.
