Synchronizing erbium-doped fiber dual-ring lasers by using the method of feedback modulating-parameter
基于反馈参数调制的掺铒光纤激光器混沌同步

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 phase-vagueness automatically. Numerical simulation shows that two hyperchaotic erbium-doped fiber dual-ring lasers can be identically synchronized, when the feedback intensity is suitably selected.
