Abstract

We demonstrate a novel type of stable multicomponent vector solitons consisting of two perpendicular four-wave mixing (FWM) dipole components induced by electromagnetically induced gratings. We analyze the formation and steering of the steady dipole solitons and their dynamical (energy transfer) effects. The dipole-mode solitons of two FWM processes have horizontal and vertical orientations, respectively. Omnidirectional Bragg reflections are also investigated.

摘要

我们展示了一种新型的稳定多分量矢量孤子，它由两个相互垂直的四波混频（FWM）偶极子分量组成，这两个分量是由电磁感应光栅引起的。我们分析了稳态偶极子孤子的形成和转向及其动力学（能量转移）效应。两个 FWM 过程的偶极子模式孤子分别具有水平和垂直取向。还研究了全方向布拉格反射。
