| 摘 要： | 分析了信号光入射后可能发生的效应基于电磁场理论,综合光纤受激喇曼散射(SRS)效应、建立了光纤喇曼放大泵浦光与斯托克斯光、信号光的关联方程,给出了系统增益形成正反馈条件的表达式,结果表明:在光纤参量满足增益正反馈的条件下,当SRS增益对应于非饱和增益工作状态时入射信号光得到放大,SRS增益愈高则放大倍数愈高,并有区段上SRS增益相对低时其关联程度相对高. |

| Abstract: | Potential effects were analyzed after incidence of signal wave firstly. Based on the electromagnetic theory and combined with the nonlinear effect of Stimulated Raman Scattering (SRS) of optical fiber, correlative equations were set up for the Raman amplifying pump wave of optical fiber, Stokes wave and signal wave and the conditional expression which made system gain form positive feedback was given at the same time. It comes to the conclusion that under the condition that system gain positive feedback is satisfied by optical fiber parameters, the input signal wave is amplified when the SRS gain corresponds to unsaturated gain state; the higher is the SRS gain the more is amplification times ; the correlation degree is relatively increased when the SRS gain is relatively low in some region. |
| Keywords: | Fiber Raman amplification Correlation between pump wave and signal wave Correlation function |
