贝塞尔光子晶格中的旋转偶极模孤子

On the Generation of Topological Vector Solitons from Bessel Like Beams

Coupled solitary waves in optics literature, are coined vector solitons to reflect their particle--like nature that remains intact even after mutual collisions. They are born from a nonlinear change in the refractive index of an optical material induced by the light intensity. We've discovered that the second harmonic intensity profile generated by Bessel like beams, is composed of solitons of various geometries surrounded by concentric rings; one of which is two central solitons of similar radius knotted by ellipsoidal concentric rings. We observe that their geometry and intensity distributio…

Swinging of two-dimensional solitons in harmonic and Bessel optical lattices

本文研究了克尔型饱和介质中纵向调制谐波晶格和贝塞尔晶格中二维空间孤子的参量放大。研究表明，在二维晶格中，孤子中心沿不同轴的振荡是耦合的，这导致了一些有趣的传播现象，包括沿垂直轴的孤子振荡的周期性阻尼和激发，沿其中一个横轴的孤子振荡的选择性放大以及孤子螺旋的增强.

耗散晶格介质中的局域模：综述

Localized modes in dissipative lattice media: An overview

本文综述了基于复Ginzburg-Landau方程的一维和二维空间耗散孤子动力学模型的理论研究，该模型包含了虚、实或复空间周期势，其中损耗项和增益项为五阶组合。虚电势表示局部损耗和增益的周期性调制。结果表明，有效的梯度力，引起的非均匀损耗分布，引起三个通用的传播场景的一维（1D）耗散孤子：横向漂移，持续摆动运动，阻尼振荡。当晶格平均损耗/增益值为零，并且实势具有与虚部相反的空间宇称时，相应的复势是宇称-时间对称的实现。在后一种晶格势作用下，一维孤子具有独特的横向漂移和持续摆动运动机制。在2D几何中，考虑三种类型的轴对称径向晶格，即，它们仅基于折射率调制、或仅基于线性损耗调制、或基于两者的组合。通过改变初始切向反冲的强度，可以有效地控制孤子在这种轴对称势场中的旋转运动。
