摘要

本文利用R.H.Stolen的实验结果

拟合得到SRS Stokes谱线的多项式近似表达式.该表达式精度较高

有一定的理论价值.在此基础上

研究了不同光纤的Raman增益和噪声指数.结果表明增益和噪声指数差异主要由光纤的有效纤芯面积引起

因而有效纤芯面积最小的G.653光纤Raman增益和噪声指数最大.

Abstract

An approximate polynomial of the SRS Stokes spectrum is obtained by digitized fit from the experimental measurements of R.H.Stolen.It has some theoretical value with its certain precision.Upon the Stokes spectra formulae

we researched the Raman gain and Noise figure in Raman amplifier with different fibers.It shows that the difference of the gain and noise figure is contributed by the effective core area of different fibers.
