摘要

数值仿真分析了利用高非线性光纤（HNLF）的交叉相位调制（XPM）效应实现归零（RZ）码到非归零（NRZ）码的转换

并讨论了RZ信号占空比、光纤色散对转换后NRZ信号Q因子的影响。数值结果表明:转换后NRZ码的Q值受输入RZ信号占空比的影响;而且RZ信号与连续的探测光之间的色散差也严重影响转换后NRZ信号的Q因子值。

Abstract

We numerically analyze all-optical RZ to NRZ format conversion based on the Cross-Phase Modulation（XPM） in Highly Nonlinear Fiber（HNLF） and discuss the duty cycle of the RZ signals and the effects of the Q factor of fiber dispersion on the converted NRZ signals.Simulation results show that related higher Q factor can be obtained by carefully selecting the duty cycle of the input RZ signal and decreasing the dispersion difference between the RZ signal and continuous probe light.
