摘要 分别优化C和L两个波段掺铒光纤放大器,利用并联方式实现了C+L-波段超宽带光纤放大器.研制出了一台结构简单、高增益低噪声、增益平坦的超宽带掺铒光纤放大器,实现了从1 524 nm-1 602 nm超过 70 nm带宽内平均增益,其中C-波段在1 524nm-1 564 nm之间平均增益超过30 dB,L-波段从1 572 nm到 1 602 nm增益起伏小于2 dB. In this paper, we utilized optimized C-band and L-band amplifiers to constitute a broadband C+L erbium-doped amplifier With a parallel structure. This amplifier has a simple configuration, high-flattened gain and low noise. Meanwhile, we have realized an amplification bandwidth of over 70 nm(1 524~1 602 nm)without any broadband gain flattening component. The C-band average gain is over 30 dB and L-band gain variation is less than 2 dB.
