摘要
利用后向ASE抽运一段未抽运光纤和一段不完全抽运光纤两种结构,实现了EDFA自发辐射谱向长波方向移动,分别得到了3 dB带宽为56.3 nm和47.6 nm的L-波段自发辐射谱,对1575 nm输入信号(强度为-30 dBm)的增益分别为3.5 dB和9.2 dB.
Abstract
3 dB bandwidths of 56.3 nm and 47.6 nm of ASE spectra have been respectively obtained by using backward ASE pumping an unpumped EDF and a weak pumped EDF. The gain is 3.5 dB and 9.2 dB for a small input signal of 1575 nm, respectively.
