摘要

基于SOA交叉增益调制效应(XGM)进行了2.5Gbit/s 31位非归零(NRZ)伪随机码的全光波长转换实验

分析了该方案下转换信号的消光比、信噪比、平均功率与输入连续光、信号光功率、波长的关系.实验中转换信号的光信噪比可达40dB以上

消光比和信噪比均大于10dB

符合ITU-T G.691标准.信号波长向下转换间距可达60nm

是目前基于SOA中的XGM效应进行波长转换获得的最大的波长间距.

Abstract

All Optical Wavelength Conversion(AOWC)of 2.5Gbit/s non return-to-zero(NRZ)data based on cross-gain modulation(XGM)in a semiconductor optical amplifier(SOA)is demonstrated.The experiment shows that the power and wavelength of input light have great influence on extinction ratio(ER)

signal to noise ratio(SNR)and average power of converted signal.Optical SNR of converted signal is larger than 40dB.ER and SNR of detected signal are both larger than 10dB

meeting ITU-T G.691 standard.The wavelength separation for down-conversion is larger than 60nm.This is the largest separation achieved from wavelength down-conversion based on XGM in SOA.
