A method for controlling hyperchaos of Er-doped fiber laser--Nonlinear time-delay feedback modulating-parameter
一种控制掺铒光纤激光器超混沌的方法——非线性延时反馈参数调制法

We present a method of nonlinear time-delay feedback modulating-parameter to control chaos/hyperchaos.A scheme of controlling the hyperchaotic dual-ring Er-doped fiber laser by using this method is proposed.Numerical simulation shows that a hyperchaotic dual-ring Er-doped fiber laser can be successfully controlled into different periodic states by this method only when the delay time and feedback intensity are suitably matching.
