Abstract

Both imaginary value off-axis solitons and imaginary value off-axis vortex solitons are analytically obtained in nonlocal nonlinear media. The imaginary value off-axis solitons can do the snakelike propagations resulting from that the soliton phase \(\Theta \) are period functions, and the propagation paths (including propagation directions and reverse points) of such solitons can be controlled by selecting the appropriate imaginary values b and c. Due to the position-changed vortex phase, the imaginary value off-axis vortex solitons revolve clockwise or counterclockwise along the controllable elliptical trajectories of different orientations depending on their imaginary off-axis shifts. The controllable vortexes may be used as optical tweezers and wrenches, and the controllable mass centers may have potential application in all-optical controlling.

虚值离轴涡旋孤子在非局部非线性介质中的可控传播路径

摘要

虚值离轴孤子和虚值离轴涡旋孤子都是在非局部非线性介质中解析获得的。虚值离轴孤子可以做蛇形传播，这是由于孤子相位\（\ Theta \）是周期函数，并且可以通过选择适当的值来控制此类孤子的传播路径（包括传播方向和反向点）虚值b和c。由于位置改变了涡旋相位，虚值离轴涡旋孤子根据其虚轴移而沿不同方向的可控椭圆形轨迹顺时针或逆时针旋转。可控制的涡流可用作光镊和扳手，并且可控制的质心可能在全光控制中具有潜在的应用。
