摘　　要：阐述了非线性光环路镜 ( NOLM)的基本原理 .通过研究它的光学特性 ,我们发现 ,由于自相位调制 ( SPM) ,NOLM有压缩光脉冲脉宽的功能 .因为光的克尔效应是瞬时的 ( 2～4fs) ,所以 NOLM的这种功能在高速光纤通信系统中有潜在的应用前景 .In this paper, the fundamental principle of nonlinear optical loop mirror (NOLM) is expatiated, the characteristic of NOLM is studied. Firstly, we find that NOLM has a function of compressing optical pulse width, self-phase modulation (SPM) in NOLMs is a crucial reason. Because optical Kerr effect is instantaneous (2～4 fs), this function of NOLM is potentially applicable for high-speed optical fiber transmission system.
