Gold Helix Photonic Metamaterial as Broadband Circular Polarizer
Justyna K. Gansel,Michael Thiel,Michael S. Rill,Manuel Decker,Klaus Bade,Volker Saile,Georg von Freymann,Stefan Linden,Martin Wegener +8 more
TL;DR: This work investigated propagation of light through a uniaxial photonic metamaterial composed of three-dimensional gold helices arranged on a two-dimensional square lattice that is scalable to other frequency ranges and can be used as a compact broadband circular polarizer.
Journal ArticleDOI
Past achievements and future challenges in the development of three-dimensional photonic metamaterials
TL;DR: In this paper, the authors describe recent progress in the fabrication of three-dimensional metamaterial structures and discuss some of the remaining challenges, including ultra-high-resolution imaging systems, compact polarization optics and cloaking devices.
Journal ArticleDOI
Magnetic Response of Metamaterials at 100 Terahertz
Stefan Linden,C. Enkrich,Martin Wegener,Jiangfeng Zhou,Thomas Koschny,Thomas Koschny,Costas M. Soukoulis,Costas M. Soukoulis +7 more
TL;DR: The measured optical spectra of the nanofabricated gold structures come very close to the theoretical expectations and additional numerical simulations show that the structures exhibit a frequency range with negative permeability for a beam configuration in which the magnetic field couples to the LC resonance.
Journal ArticleDOI
Three-Dimensional Invisibility Cloak at Optical Wavelengths
TL;DR: A three-dimensional invisibility-cloaking structure operating at optical wavelengths based on transformation optics is designed and realized and uses a woodpile photonic crystal with a tailored polymer filling fraction to hide a bump in a gold reflector.
Journal ArticleDOI
Direct laser writing of three-dimensional photonic-crystal templates for telecommunications
M. Deubel,Georg von Freymann,Martin Wegener,Suresh Pereira,Kurt Busch,Kurt Busch,Costas M. Soukoulis +6 more
TL;DR: The fabrication—through direct laser writing—and detailed characterization of high-quality large-scale f.c. c.
