摘　　要：研究了光纤反常色散区非线性环形镜 (NOLM)的脉冲透过特性 ,得到NOLM周期性透过率函数第一极大值处透过率、压缩比和对应的孤子阶数与环长之间的函数关系图 .通过比较长环和短环NOLM对无啁啾、啁啾脉冲的透过率和压缩比特性 。We have studied the pulse transmission properties in a nonlinear optical loop mirror (NOLM) with abnormal despersion and obtained the first maximum of transmission, the compression ratio and related soliton order at the first maximum as functions of nomarlized loop length. With the comparison of transmission and compression properties of both transmission limited and chirped pulses in long and short loop loop length NOLMs, we conclude that long NLOM is fit for pulse shaping, while short NOLM is fit for pulse compression.
