摘要
对多波长抽运增益平坦拉曼光纤放大器设计中需考虑的重要问题进行分析,包括光纤类型差异和掺杂浓度对拉曼增益系数的影响等,并通过数值计算得到了不同波长抽运光随光纤长度的演变情况,进而给出了多波长抽运情况下抽运波长的选择方法,估算了抽运光的所需能量。
Abstract
Important issues on designing multi-wavelength pumped gain flatness of fiber Raman amplifiers (FRA) are analyzed, including effects of fiber type and doping concentration on Raman gain coefficient. Through numerical computation, evolutions of pump beams with different wavelength along with fiber length are acquired. Moreover, methods for selecting wavelengths and estimating pump power of each selected wavelength in multi-wavelength pumped gain flatness FRA are presented.
