适合WDM网络动态增益均衡的全光增益锁定光纤放大器

All optical Gain clamped in Line Fiber Amplifier for Dynamic Gain Equalization of WDM Networks

在光纤放大器内部同时建立增益谱锁定与平坦机制，研制出适合ＷＤＭ网络应用的全光锁定高增益、大功率掺铒光纤放大器（ＥＤＦＡ）。在２３ｄＢ输入功率动态范围（－４０～－１７ｄＢｍ）内的增益箝制在３３ｄＢ，对应总输入功率为－１７ｄＢｍ的输出光功率为１６ｄＢｍ，锁定的－１ｄＢ增益带宽为１４ｎｍ（１５４７～１５６１ｎｍ）。

An all optical gain clamped and flattened fiber amplifier is reported. This technique is applicable for WDM networks with dynamic gain equalization of high gain, high power EDFAs. The dynamic range reaches 23 dB (-40￣-17 dBm) for a constant 33 dB gain, while the -1 dB gain bandwidth is 14 nm (1547￣1561 nm). The output signal power is 16 dBm.
