Polarization multiplexing and bifocal optical vortex metalens
In this article, we demonstrate several optical vortex metalens (OVMs) based on the Pancharatnam–Berry (PB) geometric phase concept utilizing silicon nanobricks. The nanostructured OVMs are designed via coalescing the phase profiles of metalens and vortex phase plate, which can produce and focus the...
