摘　　要：提出了一种用ASE宽带光源调节拉曼光纤放大器(RFA)增益平坦的简单方法.将该ASE宽带光源调节RFA增益平坦所得泵浦配置方案用于DWDM信号的放大,得到DWDM信号增益谱与相应波长处ASE信号的增益谱相近,且增益波动小于1dB.所用的方法结构简单,调节方便,可有效地调节利用RFA的DWDM系统增益平坦度,而不需要调节复杂、成本昂贵的DWDM信号源.A simple method is proposed to adjust Raman fiber amplifiers' gain flatness by means of a broadband amplified spontaneous emission (ASE) light source. The gain ripple of 20-channel is below 1 dB, and the gain spectrum is nearly the same with the ASE's when the same pump deployment is used. The method is simple and easy to operate and can be utilized to optimize the performance of the Raman fiber amplifier used in DWDM system without using expensive DWDM signal source whose operation is complicated.
