Generation of Power-Exponent-Phase Vortex Beam Arrays Based on All-Dielectric Metasurfaces

Optical vortices (OV) with an open shape have a unique function in directional particle transport and collection. A power-exponent-phase vortex (PEPV) has received particular attention as a type of unconventional vortex beam with a large opening and carrying orbital angular momentum (OAM). So far, o...
