Abstract

In this research, we investigated tight focusing of vector beams with negative orders. It is theoretically proven that the lengthwise component of the spin angular momentum is equal zero near the focal area only for the first order of the incident beam. It was shown using numerical simulations and Debye integrals that local subwavelength regions with circular and elliptic polarization of opposite signs are formed in front of and behind the focal plane.

负阶圆柱矢量光束尖焦点附近的霍尔效应

在这项研究中，我们研究了负阶矢量光束的紧聚焦。理论证明，只有一阶入射光束的自旋角动量的纵向分量在焦区附近等于零。数值模拟和德拜积分表明，在焦平面前后形成了具有相反符号的圆偏振和椭圆偏振的局部亚波长区域。
