摘要

基于矢量角频谱表示法，研究了高阶波恩卡莱球上矢量涡旋拉盖尔-高斯光束的传播波和蒸发波在非平行状态下的贡献。传播波和蒸发波的演化特性与拓扑电荷、径向阶数、椭圆度角和腰宽密切相关。详细讨论了蒸发波对矢量涡旋束的强度、自旋和轨道角矩的影响。

Effect of evanescent wave on vector vortex beams on higher-order Poincaré sphere

Based on the vector angular spectrum representation, the contributions of the propagating and evanescent waves to the vector vortex Laguerre–Gaussian beams on the higher-order Poincaré sphere are investigated in the nonparaxial regime. The evolution properties of the propagating and evanescent waves are closely related to the topological charge, the radial order, the ellipticity angle, and the waist width. The influences of the evanescent waves on the intensity, the spin and orbital angular momenta of the vector vortex beams are discussed in detail.
