Abstract
Plasmonic metamaterials exhibit strong and tunable dispersion, as a result of their pronounced resonances. On page 6300, Thomas Pertsch and co-workers show how the dispersive properties of a metamaterial with fishnet geometry can be used to design an ultrathin light-shaping element. The device produces different holographic images at two distinct wavelengths in the near IR range.

Additional Information
Controlling and engineering light-matter interactions establish and crucial link between fundamental and applied research. Innumerable investigations of nature rely on light as a tool and messenger for studies of the shortest time scales as well as the largest structures in the universe. Recent advances in the manipulation and control of light by man-made photonic nanomaterials are enabling innovative applied research in an increasing number of scientific branches. Gaining full access on all the properties of light by the help of advanced and miniaturized optical components is one of the prime interests within publicy-funded collaborative projects, like the German research initiative on photonic nanomaterials (www.phona.uni-jena.de).
In this recent contribution from scientists of the Friedrich-Schiller-Universitat Jena (Germany), it is shown for the first time how a photonic nanomaterial can be used as a hologram enabling a hyperspectral display of information. The techniques used herein are directly applicable to large-scale manufacturing platforms for optical elements and pave the way for simultaneous spatial and spectral control of light. Future holograms from photonic nanomaterials have obvious applications in broad-band pattern generation as required for adaptive optics, multidimensional imaging, microscopy, optical data storage, as well as in cryptography and security applications.
