摘要
基于非线性FP腔 (NOLF)双稳效应 ,提出一种利用掺铒光纤放大器 (EDFA)及NOLF对经DSF压缩后的超短光脉冲进行消基座的方案 .利用耦合模方程 ,分析了NOLF的消基座特性 .结果表明 ,通过合理选择NOLF的反射率、入射脉冲的中心频率与NOLF的共振频率的失谐量及EDFA的增益 ,可使脉冲的基座能量比减小一半 .
Based on the bistability effect of nonlinear FP cavity (NOLF), a method is suggested to suppress the pedestal of ultra-short optical pulse compressed by dispersion shift fiber (DSF). The coupled mode equation is applied to analyze the characteristics of the pedestal suppression of NOLF. The results show that the pedestal energy ratio of transmitted pulse can be decreased to half of incident pulse through reasonably selecting the facet reflectivity of NOLF, the initial phase detuning between the input pulse and NOLF, and the gain of Er-doped fiber amplifier.
