光束在非局域垒影响下的动力学行为

我们提供了基态和多极(偶极和三极)光束在非局域程度呈垒型分布的非均匀非局域介质中传输的动力学演化行为。在非局域垒的影响下,基态光束会发生周期性振荡,其振荡周期和振荡程度可以由非局域垒的系统参数进行调控。然而,多极光束在非局域垒的影响下会分裂成相应数目的基态光束,分裂形成的各基态光束在传播过程中发生周期性碰撞;通过调控系统参数,其碰撞周期和振荡程度可以被有效控制。

Abstract

Dynamical behaviors of optical beams including fundamental and multi-polar solitons in barrier-type nonlocal nonlinear system are presented. Under the influence of barrier-type nonlocality,fundamental soliton experiences periodic oscillations,and its period and degree of oscillation can be effectively controlled by adjusting the parameters of barrier-type nonlocal system. However,for multi-polar soliton,it splits into a corresponding number of fundamental solitons due to suffering from a barrier-type nonlocality; and,these fundamental solitons periodically collide each other during their propagation; their dynamical behaviors can also be controlled by adjusting the parameters of barrier-type nonlocal system.
