Influence of the third-order dispersion on nonlinear propagation properties of optical gaussian shaped pulses in monomode optical fibers

应用变分法 ,研究了三阶色散对高斯脉冲在单模光纤中的非线性传输特性的影响 ,导出了高斯脉冲参数的演化方程组。在此基础上 ,讨论了三阶色散和初始啁啾对脉冲宽度的影响。

The influence of the third-order dispersion on nonlinear propagation properties of optical Gaussian shaped pulses is investigated in monomode optical fibers by means of variational method,and the evolution equations for the parameters of the optical Gaussian shaped pulse is derived.By these equations,we discussed the properties of the parameters.
