摘　　要：针对目前全光波长变换大多是利用半导体光放大器来实现的现状,本文提出了基于掺饵光纤放大器(EDFA)和非线性色散光纤(NDF)的全光波长变换。该方法利用抽运光和信号光同时输入NDF中时,NDF中产生的四波混频效应(FWM)能有效的产生新的光波,从而实现全光波长变换。文中首先介绍了利用OptiSystem软件成功实现了全光波长变换的仿真,接着在实验室中通过利用掺饵光纤放大器以及G655实现了全光波长变换。获得了最高-16.7dB的变换效率。实验结果表明,无论是理论模拟还是在实验室均获得了清晰明显的波长变换波形。Since the all-optical wavelength conversion at present is realized by using Semiconductor Optical Amplifier （SOA）, the all-optical wavelength conversion based on Erbium-doped Fiber Amplifier and Nonlinear Dispersion Fiber （EDFA＋NDF） is put forward in the paper. When the pump and signal lights input the NDF, Four Wave Mixing （FWM） in NDF can produce new light in the nonlinear dispersion fiber. By using the OptiSystem software, the simulation of the all-optical wavelength conversion is achieved. And then, the all-optical wavelength conversion is realized through the EDFA and the G655. The conversion efficiency of -16.7dB is acquired. The experiment result indicates that sharp wavelength conversion picture is obtained both in theoretical simulation and lab
