| 摘 要： | 提出了泵浦分配两段级联,并利用前向ASE推动下一级EDF工作的L-Band放大器的新结构.基于Giles模型并考虑了ASE噪声的影响,运用数值模拟算法系统分析了泵浦光功率分配和铒光纤分配比例对这种EDFA性能的影响.最后优化得到高增益且增益谱平坦的L-Band EDFA,其在输入信号光功率为-20 dBm时,在1571～1608 nm范围内,增益值高达35 dB,增益偏差小于1 dB.

| Abstract: | A new structure of L-Band EDFA with two-stage pumps is introduced. The new structure utilizes the forward ASE (amplified spontaneous emission) as a second pump. Based on the Giles model with ASE, the influence of the pump power ratio and the length of EDF on the characteristics of this EDFA is studied numerically. The present EDFA structure can achieve 35 dB gain with only about 1 dB gain ripple (from 1571 nm to 1608 nm) when the input signal is fixed at -20 dBm. |
