摘要/Abstract

摘要： 基于非局域非线性介质中空间光孤子的理论模型，采用分部傅里叶算法，我们研究了空间孤子在二维非局域非线性介质中的传输特性及其稳定性。结果表明，在该介质中存在Laguerre-Gauss（拉盖尔-高斯）型的空间孤子；孤子的传输特性受非局域介质的调制系数、调制深度，以及光束的初始条件等调控，并且传输距离的越大，影响越显著。本文的结果对完善和充实空间孤子理论体系有重要意义。

Abstract: Based on the basic theory model of spatial optical solitons in no-local nonlinear medium, using the subsection Fourier algorithm, we study the transmission characteristics and stability of the spatial optical solitons in two-dimensional no-local nonlinear media. Our results reveal that in the medium, Laguerre Gauss soliton (LGs) can exist. The transmission properties of soliton can be controlled by the modulation depth coefficient, as well as the initial conditions of beam condition in the no-local media. Furthermore, we found that the bigger of the transmission distance, the greater the effect significant is. The results of this paper can improve and enrich the spatial soliton theory system.
