摘要

本文对三维矢量圆柱旋转对称电磁波在各向同性非线性介质中的传播,采用改进的时域有限差分广义矢量辅助微分方程方法,对非线性极化矢量、单位体积的非线性偶极矩(包括各向同性部分和各向异性部分)进行了理论和仿真研究。提出了横向磁和横向电两种情况下的理论,并给出了组合方程。给出了假设纯各向同性极化矢量时,BK7中横向电空间孤子传播的模拟结果,以及熔融石英中横向电空间孤子和横向磁空间孤子传播的模拟结果。给出了二硫化碳中横向磁孤子和横向电孤子传播的仿真结果,包括极化矢量的各向异性部分。

General vector auxiliary differential equation finite-difference time-domain method for rotationally symmetric vector wave propagation in nonlinear optics.

In this paper, the theory and simulation results are presented for 3D vector cylindrical rotationally symmetric electromagnetic wave propagation in an isotropic nonlinear medium using a modified finite-difference time-domain general vector auxiliary differential equation method for nonlinear polarization vectors, the nonlinear dipole moment per unit volume, including both an isotropic part and an anisotropic part. The theory is presented for both the transverse magnetic and transverse electric cases, along with the combined equations. The simulation results for transverse electric spatial soliton propagation in BK7, and the simulation results for transverse electric and transverse magnetic spatial soliton propagation in fused silica, assuming a purely isotropic polarization vector, are shown. The simulation results for both transverse magnetic and transverse electric spatial soliton propagation in carbon disulfide, including the anisotropic part of the polarization vector, are also shown.
