Abstract


The dispersive nature of plasmonic metamaterials and their ability to tailor the optical response rendersĀ  them promising candidates for versatile optical elements. Here we present new approaches how optical metamaterials can be used to achieve complex diffractive elements, i.e. holograms. Besides the theoretical and numerical exploration of devoted encoding schemes for these elements, we present experimental results concerning the fabrication and the characterization of metamaterial holograms. For the first time, we demonstrate metamaterial holograms operating simultaneously at different wavelengths.
