| 摘 要： | 针对基于光纤自相位调制效应的全光再生技术,分析了色散效应对再生器转移函数和Q因子改进量的影响以及再生器中色散和自相位调制的相互作用,提出一种通过改变再生器光纤结构实现转移函数平坦区改善的方法。数值结果表明:全光再生器中色散会抑制自相位调制引起的频谱展宽,使Q因子改进量减小;对于色散,非线性系数和长度等参量不同的光纤介质,如果色散与长度的乘积与最大非线性相移的比值一定,再生器的性能基本不变;在两段高非线性光纤间增加适当长度色散补偿光纤,可以改善转移函数平坦区,使平坦区范围显著增加。

| Abstract: | Aiming at the all-optical regeneration based on self-phase modulation effect(SPM) in fiber,the effect of the chromatic dispersion on the transfer function and Q factor improvement of the regenerator was analyzed,as well as the interaction between chromatic dispersion and SPM.The method to improve the plateau of transfer function via changing the segments of fiber in the regenerator was proposed.The numerical results show that chromatic dispersion will suppress the spectra broadening caused by SPM and reduce... |
