摘要

采用小信号分析方法研究了色散和非线性共同作用下的光信号传输

导出了损耗、色散、自相位调制及交叉相位调制作用下反映交叉相位调制过程的频域传递函数

通过该传递函数给出了在强度调制直接检测系统中确定任意泵浦信号下的探测波时域波形的解析方法

发现泵浦波自相位调制一定程度上增大了频域传递函数

且增大程度随着调制频率、输入信号平均功率及传输距离的提高而逐渐变大

解析结果和数值仿真能较好吻合.

Abstract

The transmission of optical signal under the effect of dispersion and nonlinearity is investigated by small signal analysis.Frequency domain transfer function (FDTF) is given which include loss

dispersion

self phase modulation (SPM) and cross phase modulation (XPM) and reflects XPM process.The analytical method to determine the time domain shape of probe wave when arbitrary pump wave is inputted is confirmed in intensity modulation direct detection system.We find that the SPM in pump channel increases FDTF to some extent and the increased extent is enhanced with the increase of modulation frequency

average power of input signal and transmission distance.The analytical result agrees well with numerical simulation.
