Abstract

We present a comprehensive review on the geometric-phase based metasurfaces for orbital angularmomentum(OAM) generation and detection. Thesemetasurfacesmanipulate the electromagnetic (EM) wave by introducing abrupt phase change, which is strongly dependent on the polarization state of incident EMwave and can be interpreted by geometric phase. Hence, the conventional bulk devices that based on the accumulated phase change along the optical path can be avoided.
