  • 摘要:在通信领域,特别是波分复用方面,为了同时调整多通道增益和实现多波长光纤 器大范围稳定的光波输出,本文提出了一种未泵浦掺铒光纤Sagnac环透射端掺铒光纤放大器增益平坦特性研究方案,其由Sagnac环自身谐振模式、未泵浦掺铒光纤的吸收特性和由环中双折射拍长引起的谐振模式3者共同作用。通过调节Sagnac环中的偏振控制器,使得掺铒光纤放大器(EDFA)增益光谱在非泵浦掺铒光纤Sagnac环透射端可以被部分或者全部平坦化。实验结果表明:在透射端14 nm的波长范围内,部分增益光谱的平坦度为±0.145 dB;整个C波段光谱36.5 nm的波长范围内,增益光谱的完全平坦度为±1.225 dB。该增益谱平坦方案结构简单,输出光谱平坦度好,有望用于波分复用系统和多波长 器中。
