摘　　要：文章比较了3类色散渐减光纤环镜的光脉冲压缩特性,结果发现,不考虑高阶效应时,线性渐减光纤环镜需要的最佳光纤长度最短,压缩后的光脉冲质量较高;考虑高阶效应后,情况恰恰相反,高斯渐减光纤环镜需要的最佳光纤长度最短,压缩质量较高,但此时3种类型的光纤构成的非线性光纤环镜压缩特性差别不大。Comparisons are made of the pulse compression characteristics of the nonlinear optical loop mirror constructed from three types of dispersion decreasing fibers. The results show that the linear dispersion profile fiber loop is optimal when high-order effects are not considered, while the Gaussian dispersion profile fiber loop is optimal when high-order effects are considered. However, the difference is not very distinct in this case.
