Abstract

Optical metasurfaces enable the most general spin-orbital momentum transformations that map the higher order Poincaré sphere. I will first review our work on metasurfaces spin-to-orbital momentum converters that allow beam control and structuring. I will then introduce our latest results in the creation of coupled lasers with design OAM and topology.
