L波段EDFA的优化设计和实验验证

Optimization Design of L-band EDFA and Experimental Validation

摘要:

基于Giles模型，对L波段掺Er光纤放大器(EDFA)的特性进行了数值模拟，分析了采用高掺杂Er纤放大器输出性能的改善。根据数值分析的结果进行了优化设计，使用9m长的高掺杂Er光纤进行了实验研究。实验结果表明．在泵浦功率为100mw时，小信号增益在10dB以上，噪声指数小于6dB。

Abstract:

The configuration parameters of L-band erbium-doped fiber amplifiers(EDFA) was optimized and the influence of high concentration of Er on output character of the EDFA was studied by numerical simulations based on Giles model.The experimental results accord with our optimization design well for the EDFA with the high concentration of Er and length of 9 m.Its small signal gain is more than 10 dB and its noise figure is less than 6 dB with pump power of 100 mW.
