摘要
提出了一种基于反馈参数调制控制超混沌同步的方法,并应用于双环掺铒光纤激光器系统.针对此种方法所具有的相位模糊问题,设计出了自动消除反相位的电路,数值模拟表明只要适当选择反馈强度值,就能实现两双环掺铒光纤激光器系统的精确同步.
A method of feedback modulating-parameter is presented to synchronize hyperchaotic systems, and is applied to the hyperchaotic erbium-doped fiber dual-ring laser systems. A circuit is designed in the laser synchronization system to avoid phasevagueness automatically. Numerical simulation shows that two hyperchaotic erbium-doped fiber dual-ring lasers can be identically synchronized, when the feedback intensity is suitably selected.
