Device for Modifying And/or Controlling the State of Polarisation of Light

The present invention concerns a device for modifying and/or controlling the state of polarisation of light, said device comprising a light impervious surface structure provided with at least one through hole or aperture and with a surface topography comprising one or several surface features which are arranged periodically or quasi-periodically around said hole or aperture or around each of said holes or apertures and designed to interact in a resonant manner with the transmitted light. Device characterised in that the surface topography around the or each hole consists of a grating selected among elliptical and chiral gratings.
