摘要
利用延时反馈一注入法研究了具有泵浦光强调制的单环掺饵光纤激光器的混沌同步。数值模拟表明,在合适的反馈和注入条件下,两个单环掺铒光纤激光器能够达到混沌同步。即使存在一定的高斯噪声影响,两个激光器仍然能够达到较好的同步。在此基础上,进一步研究了掺铒光纤激光器中参数不匹配情况对混沌同步的影响。
The chaotic synchronization of erbium- doped fiber ring laser with pump modulation using delay feedback - injection scheme have been investigated. Numerical simulation shows that the two erbium - doped fiber ring lasers can be well synchrtonized if the strengths of delay feedback and injection are suitable. Even though the effects of the gauss noises are considered, they still reach good synchronization. Also, the influence of parameter mismatches on chaos synchronization is investigated.
