Abstract

The process of focusing circularly polarized laser beams by plane diffractive lenses using the Richards-Wolfe formula is considered. It is established that in the focal plane of a light field with circular polarization circles of different radii with the center on the optical axis are formed. In these circular regions polarization vectors are twisted in opposite directions. The appearance of “spin” separation depending on the radius can be explained by the phenomenon of radial spin Hall effect in the focal plane.

圆偏振光束的霍尔效应

考虑了利用Richards-Wolfe公式用平面衍射透镜聚焦圆偏振激光束的过程。建立了在具有圆偏振的光场的焦平面中，形成了以光轴为中心的不同半径的圆偏振。在这些圆形区域中，极化矢量在相反的方向上扭曲。“自旋”分离的出现取决于半径，可以用焦平面中的径向自旋霍尔效应现象来解释。
