发布时间：2018-09-09 18:06

【摘要】：非局域空间孤子具有低功率、类似粒子的弹性碰撞特性,因此在光信息处理和光连接领域具有潜在应用。为了获得光束传输的有效控制方法,数值计算了亮孤子及亮孤子对由非局域介质进入竞争非局域介质后的传输行为。发现,非局域亮孤子进入竞争非局域介质后以呼吸子的形式传输。非局域偶极孤子进入竞争非局域介质后分裂成两个独立传输的亮孤子。反位相非局域亮孤子组成的震荡束缚态进入竞争非局域介质后的传输行为与界面(非局域介质与竞争非局域介质的交界)位置有关。当界面选到节点(非局域孤子间距离取最小值的点)附近时,震荡束缚态分裂成两个独立的孤子;界面选到其它位置时,震荡束缚态以准束缚态形式传输。该发现为光的传输与控制提供了新的方法。
[Abstract]:Non-local spatial solitons have low power, similar to the elastic collision characteristics of particles, so they have potential applications in the field of optical information processing and optical connection. In order to obtain an effective control method for beam propagation, the propagation behavior of bright solitons and bright solitons from nonlocal media to competing nonlocal media is numerically calculated. It is found that the nonlocal bright solitons propagate in the form of respiratory elements after entering the competing nonlocal media. The nonlocal dipolar solitons split into two bright solitons propagating independently after entering the competing nonlocal media. The transport behavior of the oscillatory bound state composed of non-local bright solitons in the inverse phase is related to the position of the interface (the junction of the non-local medium and the competing non-local medium) after entering the competing non-local medium. When the interface is located near the node (the minimum distance between nonlocal solitons), the oscillatory bound state is split into two independent solitons, and when the interface is selected to other positions, the oscillatory bound state propagates in the form of quasi bound state. This discovery provides a new method for the transmission and control of light.
