摘　　要：作为一种人工微纳器件,超表面能够对光束的传播和相位进行精确的调控。具有不同偏振矢量特性的涡旋光束具有独特的光场分布特性,利用超表面生成复杂状态的矢量涡旋光场具有越来越广泛的研究前景。本文针对产生矢量涡旋光束超表面的材料进行分类,介绍了金属超表面、全介质超表面和智能超表面在矢量涡旋光束生成和调控方面的研究进展。我们详细阐述了超表面利用不同相位理论对入射波前调制的原理和超表面生成的不同矢量涡旋光束的特性,并探讨了这两者之间的联系。此外,我们总结了利用超表面代替传统光学器件生成矢量涡旋光束的优势,并展望了未来利用不同材料的超表面进行矢量光场调控研究方面的挑战和可能性。As an artificial micro-nano device,metasurfaces can precisely manipulate the propagation and phase of light beams.Vortex beams with different polarization vector properties possess unique optical field distribution characteristics,and the use of metasurfaces to generate complex vector vortex fields has increasingly broad research prospects.This article classifies materials for producing vector vortex beams with metasurfaces and introduces the research progress of metal metasurfaces,all-dielectric metasurfaces,and intelligent metasurfaces in vector vortex beam generation and control.We elaborate on the principles of modulating incident wavefronts using different phase theories and the characteristics of different vector vortex beams generated by metasurfaces,and explore the relationship between the two.Additionally,we summarize the advantages of using metasurfaces instead of traditional optical devices to generate vector vortex beams,and look forward to the challenges and possibilities of vector field control research using metasurfaces with different materials in the future.
