Zusammenfassung:Diffractive optical elements and methods for their fabrication are disclosed. In one aspect, a diffractive optical element is disclosed, which comprises a polymeric substrate substantially transparent to at least one electromagnetic radiation wavelength, and a plurality of metallic inclusions distributed in said polymeric substrate according to a predefined pattern such that said inclusions can collectively diffract at least a portion of incident radiation having said at least one radiation wavelength.
