Recent twists in twisted light: A perspective on optical vortices from dielectric metasurfaces
Marco Piccardo, Antonio Ambrosio
Optical vortices are the electromagnetic analogue of fluid vortices studied in hydrodynamics. In both cases the traveling wavefront, either made of light or fluid, is twisted like…

Arbitrary polarization conversion for pure vortex generation with a single metasurface
Marco Piccardo, Antonio Ambrosio
The purity of an optical vortex beam depends on the spread of its energy among different azimuthal and radial modes. The smaller is this spread, the higher is the vortex purity and…
