- Abstract
In article number 1800164, Shuqi Chen and co‐workers introduce a second harmonic Pancharatnam–Berry phase and generate one linear and two second harmonic optical vortices with different topological charges focused into different focal lengths simultaneously from the proposed metasurface, which can store three‐fold optical vortices compared with the conventional linear geometric metasurfaces. The proposed metasurface promises great applications in enhancing data capacity of optical communications and newer information security.
