摘要
研究了高阶孤子在对称结构和不对称结构的色散渐减光纤环形镜的脉冲传输特性,比较了不同耦合系数下的色散渐减光纤环形镜的开关性能及脉冲压缩性能。得出了使色散渐减光纤环具有良好脉冲输出的耦合器系数范围,对实验中参数的选取有一定的指导意义。发现不对称结构光纤环形镜亦能产生无基座超短脉冲。
The performance of a nonlinear optical loop mirror composed of a dispersion decreasing fibre（ DDF- NOLM） is investigated numerically. The switching characteristics and the pulse compression effect of the DDF - NOLM is simulated. Results show that nltroshort pedestaless pulse can also be generated when an asymmetric coupler is used, with shorter fibre needed. When proper coupler ratio is chosen, output pulse with little pedestal can be generated.
