我们提出了完美矢量涡旋光束（VVB）的概念，它不仅具有独立于偏振级和螺旋相拓扑电荷的强度分布，而且在传播时具有稳定的强度分布和偏振态（SoP）。利用萨格纳克干涉仪，我们近似生成具有局部线性和椭圆偏振的完美 VVB，并证明此类光束可以在一定的传播距离下保持其强度分布和 SoP。这些提出的 VVB 可以扩展到编码信息和量子密码，以及丰富自旋和轨道角动量的转换。 (C) 2016年美国光学学会
We propose the concept of perfect vectorial vortex beams (VVBs), which not merely have intensity profile independent of the polarization order and the topological charge of spiral phase, but also have stable intensity profile and state of polarization (SoP) upon propagation. Utilizing a Sagnac interferometer, we approximately generate perfect VVBs with locally linear and elliptical polarizations, and demonstrate that such beams can keep their intensity profile and SoP at a certain propagation distance. These proposed VVBs can be expanded to encode information and quantum cryptography, as well as to enrich the conversion of spin and orbital angular momenta. (C) 2016 Optical Society of America
