Abstract

Self-accelerating beams have the unusual ability to remain diffraction-free while undergo the transverse shift during the free-space propagation. We theoretically identify that the transverse optical field distribution of 2D self-accelerating beam is determined by the selection of the transverse Cartesian coordinates, when the caustic method is utilized for its trajectory design. Based on the coordinate-rotation method, we experimentally demonstrate a scheme to flexibly manipulate the rotation of transverse optical field for 2D self-accelerating beams under the condition of a designated trajectory. With this scheme, the transverse optical field can be rotated within a range of 90 degrees, especially when the trajectory of 2D self-accelerating beams needs to be maintained for free-space photonic interconnection.

具有指定轨迹的二维自加速光束横向光场的柔性旋转

自加速光束在自由空间传播过程中具有不受衍射影响的特性。从理论上证明了采用焦散法进行轨迹设计时，二维自加速光束的横向光场分布取决于横向笛卡尔坐标的选择。基于坐标旋转方法，实验证明了一种在指定轨迹条件下灵活控制二维自加速光束横向光场旋转的方案。利用该方案，横向光场可以在90度范围内旋转，特别是当需要保持二维自加速光束的轨迹以实现自由空间光子互连时。
