本文研究了空间衍射、非线性和抛物型渐变折射率对光纤中波传播的综合影响。本文用变分法得到了梯度折射率光纤中非线性薛定谔方程的近似解析解。特别强调的是把脉冲宽度和纵向相位延迟的变化与传播的距离沿着光纤。
The dynamics that result from the combined effects of spatial diffraction, nonlinearity, and a parabolic graded index for wave propagation in optical fibers are presented. An approximate analytical solution of the nonlinear Schrödinger equation in a graded-index fiber is obtained by using a variational approach. Particular emphasis is put on the variation of both the pulse width and the longitudinal phase delay with the distance of propagation along the fiber.
