铒镱共掺光纤放大器增益特性研究
|
摘要
利用Matlab软件和龙格-库塔算法模拟铒镱共掺光纤放大器的增益特性随入纤泵浦功率、注入信号光功率、光纤长度以及光纤内稀土离子掺杂浓度等参数的变化。研究发现,铒镱共掺光纤放大器的信号光增益随入射泵浦光功率的增大而增大,随注入信号光功率的增大而减小;放大器内光纤长度存在一个最佳值;分别注入小信号和大信号时,铒离子浓度与镱离子浓度的最佳掺杂比例分别约为1∶4和1∶8,这些对于铒镱共掺光纤放大器的优化设计具有指导意义。
The signal gain of erbium/ytterbium co-doped fiber amplifiers(EY-DCFA)as functions of pump configuration,input pump power,input signal power,fiber length,as well as the changes of concentration for rare-earth in the fiber were described by using the software of Matlab and the algorithm of Rung-Kutta.Erbium-ytterbium co-doped fiber amplifier gain of the signal light grows with the increasing of incident pump power and decreases with the growing of injected signal power.There is an optimum value of laser fiber length within the amplifier.When injected into a small value signal and a large value signal,the erbium ion concentration and the best doped ytterbium ion concentration ratio were about 1∶4 and 1∶8 respectively.These have guiding significance for the optimization design of EY-DCFA.
