  • Plasmonic plate for generating optical vortices
    Patent number: 9377617
    Abstract: A plasmonic plate for generating optical vortices, formed by electrically conducting material and defining a plurality of slots that convert a first electromagnetic field having a non-null spin angular momentum into a second electromagnetic field having a non-null orbital angular momentum.

  • Height Adjustable Phase Plate for Generating Optical Vortices
    Publication number: 20130027774
    Abstract: A phase plate including a plurality of surfaces arranged around a symmetry axis to reflect an incident electromagnetic field having a null orbital angular momentum, thereby generating a reflected electromagnetic field having an orbital angular momentum. The surfaces are arranged such that, with respect to a cylindrical reference system in which the azimuthal coordinate is measured in a plane perpendicular to the symmetry axis, the respective heights define a non-monotonic azimuthal profile, so that the reflected electromagnetic field forms an optical vortex whose topological charge is not associated one-to-one to the orbital angular momentum.
