运用数学解析法导出了关于拉曼增益与自陡峭综合效应的光脉冲传输方程,在此基础上引入洛伦兹模型将拉曼增益整合到非线性系数中来研究光脉冲中拉曼增益对自陡峭效应的作用,重点分析了高斯脉冲在各向同性光纤中传播时,拉曼增益对其自陡峭效应具体影响方式,结果表明拉曼增益会减弱自陡峭中后沿偏移程度,减小脉冲展宽,但不会影响其峰值大小. Based on the introduction of the Lorentz model, the Raman gain is integrated into the nonlinear coefficient to study the optical pulse transmission Raman gain on the self-steepening effect Steepening effect of Raman gain on the self-steepening effect of Gaussian pulse propagating in isotropic fiber is analyzed emphatically. The results show that the Raman gain will reduce the offset from steep backspan and reduce the pulse Stretch, but does not affect its peak size.
