Vortex 6.0 all-on-chip

Abstract

Optical vortices carrying angular momenta have promising applications from ultra-capacity communication to ultraprecise metrology, especially boosted by their recent on-chip developments. Now, the 6th-generation optical vortex technology has been unraveled by an all-on-chip integrated platform, with fully reconfigurable vector vortex control of arbitrary spin-to-orbital angular momentum coupling.
