Journal ArticleDOI
Materials Pushing the Application Limits of Wire Grid Polarizers further into the Deep Ultraviolet Spectral Range
Thomas Siefke,Stefanie Kroker,Stefanie Kroker,Kristin Pfeiffer,Oliver Puffky,Kay Dietrich,Daniel Franta,Ivan Ohlídal,Adriana Szeghalmi,Ernst-Bernhard Kley,Andreas Tünnermann +10 more
TL;DR: In this article, it is shown that to achieve high performance ultraviolet WGPs a material with large absolute value of the complex permittivity and extinction coefficient at the wavelength of interest has to be utilized.
Journal ArticleDOI
Enhancing second harmonic generation in gold nanoring resonators filled with lithium niobate.
Dennis Lehr,Jörg Reinhold,Illia Thiele,Holger Hartung,Kay Dietrich,Christoph Menzel,Thomas Pertsch,Ernst-B. Kley,Andreas Tünnermann,Andreas Tünnermann +9 more
TL;DR: This work demonstrates that filling gold nanorings with lithium niobate may significantly enhance its optical effects if filled with a polarizable medium, and confirms an enhancement of about 20.
Journal ArticleDOI
Circular Dichroism from Chiral Nanomaterial Fabricated by On‐Edge Lithography
TL;DR: A novel-shaped plasmonic chiral nanomaterial exhibiting circular dichroism in the near-infrared spectral range is presented and this fabrication method offers tunability of the operation bandwidth by tailoring the chiral shape.
Journal ArticleDOI
Elevating optical activity: Efficient on-edge lithography of three-dimensional starfish metamaterial
Kay Dietrich,Christoph Menzel,Dennis Lehr,Oliver Puffky,U. Hübner,Thomas Pertsch,Andreas Tünnermann,Ernst-Bernhard Kley +7 more
TL;DR: In this article, a millimeter sized array of both the planar chiral and the true 3D chiral starfish is realized, and their chiroptical performances are compared by circular dichroism measurements.
Journal ArticleDOI
Optical Modes Excited by Evanescent-Wave-Coupled PbS Nanocrystals in Semiconductor Microtube Bottle Resonators
Kay Dietrich,Christian Strelow,Constanze Schliehe,Christian Heyn,A. Stemmann,Stephan Schwaiger,Stefan Mendach,Alf Mews,Horst Weller,Detlef Heitmann,Tobias Kipp +10 more
TL;DR: This work presents a method to precisely control the number, the energy and the localization of the modes along the microtube axis and reports on optical modes in rolled-up microtube resonators that are excited by PbS nanocrystals filled into the micro tube core.
