Abstract
Vector beam has recently attracted many attentions due to novel properties and wide applications. Finding a method efficiently generating high quality vector beam is very important when it is used in practice. In this paper, we theoretically and experimentally demonstrate the generation of vector beams based on dielectric metasurfaces, which are fabricated by femtosecond laser writing in silica glass. Three types of linearly polarized vector beams are produced by three specially designed metasurfaces. The vector beam generator is convenient and robust due to its simple optical path. We believe that metasurfaces will be widely applied in manipulating polarization, phase, and amplitude of light as the development of fabrication technology.
