All-optical Wavelength Conversion based on NOLM

介绍了非线性光纤环镜的基本原理,以及利用光束传输法对耦合非线性薛定谔方程组进行数值分析,研究并搭建了采用非线性光纤环境作为介质,实现波长变换的实验系统,经实验证明,非线性光纤环路境能够将2.5 G bit/s归零码光脉冲波长变换20 nm,也能同时实现两个波长的转换。

This paper gives a mathematical description of the NOLM utilizing nonlinear Schrodinger equations.We construct an optical wavelength experiment system based on NOLM.Experimental results shows that the wavelength of 2.5 Gbit/s RZ optical pulse is successfully converted over 20 nm based on nonlinear optical loop mirror.This system can also realize the conversion of wavelength.
