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
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.
Journal ArticleDOI
Bottom-up assembly of photonic crystals
TL;DR: This tutorial review highlights fundamental aspects of the physics underpinning the science of photonic crystals, insight into building-block assembly routes to the fabrication of different photonic crystal structures and compositions is provided, and a glimpse into future applications is taken.
Journal ArticleDOI
From colour fingerprinting to the control of photoluminescence in elastic photonic crystals
André C. Arsenault,Timothy J. Clark,Georg von Freymann,Ludovico Cademartiri,Riccardo Sapienza,Jacopo Bertolotti,E. Vekris,Sean Wong,Vladimir Kitaev,Vladimir Kitaev,Ian Manners,Rongzhou Wang,Sajeev John,Diederik S. Wiersma,Geoffrey A. Ozin +14 more
TL;DR: In this article, large-area films of porous elastomeric photonic crystals (EPCs) are cycled to reversibly shift the position of the photonic band structure over a large wavelength range.
Journal ArticleDOI
Three-Dimensional Nanostructures for Photonics
Georg von Freymann,Alexandra Ledermann,Michael Thiel,Isabelle Staude,Sabine Essig,Kurt Busch,Martin Wegener +6 more
TL;DR: In this paper, a review of the progress in direct laser writing of 3D polymer nanostructures for photonics is presented, including positive and inverse 3D silicon-based woodpile photonic crystals possessing complete photonic bandgaps and novel optical resonator designs within these structures.
