摘　　要：本文提出了一种利用非线性光环镜(NOLM)进行高速光时钟提取的新方法。首先,阐述了NOLM作为光信号处理器件的工作原理。随后,搭建NOLM光时钟提取方法的仿真模型,并利用仿真对光时分复用(OTDM)下,8路10 Gb/s光传输系统进行了时钟提取。通过对仿真结果的分析,验证了该系统的工作特性。In this paper,a novel scheme by applying a nonlinear optical loop mirror（NOLM） for recovering high speed optical clock is proposed. Firstly,operation principles of the NOLM working as an optical signal processing device is described. Then,an optical clock recovery simulation setup based on NOLM is built,and performances of our proposal with 8-chanel 10 Gb/s optical time division multiplexing（OTDM） clock recovery system is verified by computer simulation. At last,analysis on simulation results and conclusions are given.
