Amorphous Photonic Lattices: Band Gaps, Effective Mass and Suppressed Transport
Mikael Rechtsman, Alexander Szameit, Felix Dreisow +4
We present, theoretically and experimentally, amorphous photonic lattices exhibiting a band-gap yet completely lacking Bragg diffraction: 2D waveguides distributed randomly accordi…
Cladding mode coupling in highly localized fiber Bragg gratings: modal properties and transmission spectra
Jens Thomas, Nemanja Jovanovic, Ria G. Becker +5
The spectral characteristics of a fiber Bragg grating (FBG) with a transversely inhomogeneous refractive index profile, differs con- siderably from that of a transversely uniform o…
Relating localized nanoparticle resonances to an associated antenna problem
Shakeeb Bin Hasan, Carsten Rockstuhl, Ralf Vogelgesang +1
We conceptually unify the description of resonances existing at metallic nanoparticles and optical nanowire antennas. To this end the nanoantenna is treated as a Fabry-Perot resona…
Homogenization of resonant chiral metamaterials
Andrei Andryieuski, Christoph Menzel, Carsten Rockstuhl +3
Homogenization of metamaterials is a crucial issue as it allows to describe their optical response in terms of effective wave parameters as e.g. propagation constants. In this pape…
An advanced Jones calculus for the classification of periodic metamaterials
Christoph Menzel, Carsten Rockstuhl, Falk Lederer
By relying on an advanced Jones calculus we analyze the polarization properties of light upon propagation through metamaterial slabs in a comprehensive manner. Based on symmetry co…
Strong influence of packing density in terahertz metamaterials
Ranjan Singh, Carsten Rockstuhl, Weili Zhang
We investigate the response of terahertz metamaterials made of split-ring resonators depending on the unit cell density. It is shown that the fundamental resonance has its highest…
Stable topological modes in two-dimensional Ginzburg-Landau models with trapping potentials
D. Mihalache, D. Mazilu, V. Skarka +4
Complex Ginzburg-Landau (CGL) models of laser media (with the cubic-quintic nonlinearity) do not contain an effective diffusion term, which makes all vortex solitons unstable in th…
Shifted-elementary-mode representation for partially coherent vectorial fields
Jani Tervo, Jari Turunen, Pasi Vahimaa +1
A representation of partially spatially coherent and partially polarized stationary electromagnetic fields is given in terms of mutually uncorrelated, transversely shifted, fully c…
Astrointerferometry with discrete optics
Stefano Minardi, Thomas Pertsch
We propose an innovative scheme exploiting discrete diffraction in a two dimensional array of coupled waveguides to determine the phase and amplitude of the mutual correlation func…
Asymmetric transmission of linearly polarized light at optical metamaterials
C. Menzel, C. Helgert, C. Rockstuhl +4
We experimentally demonstrate a three-dimensional chiral optical metamaterial that exhibits an asymmetric transmission for forwardly and backwardly propagating linearly polarized l…
Realization of a monolithic high-reflectivity cavity mirror from a single silicon crystal
Frank Brückner, Daniel Friedrich, Tina Clausnitzer +6
We report on the first experimental realization of a high-reflectivity cavity mirror that solely consists of a single silicon crystal. Since no material was added to the crystal, t…
Plasmonic modes of extreme subwavelength nanocavities
Joerg Petschulat, Christian Helgert, Michael Steinert +6
We study the physics of a new type of subwavelength nanocavities. They are based on U-shaped metal-insulator-metal waveguides supporting the excitation of surface plasmon polariton…
Geometric potential and transport in photonic topological crystals
Alexander Szameit, Felix Dreisow, Matthias Heinrich +4
We report on the experimental realization of an optical analogue of a quantum geometric potential for light wave packets constrained on thin dielectric guiding layers fabricated in…
Ultrafast spatio-temporal dynamics of terahertz generation by ionizing two-color femtosecond pulses in gases
I. Babushkin, W. Kuehn, C. Koehler +6
We present a combined theoretical and experimental study of spatio-temporal propagation effects in terahertz (THz) generation in gases using two-color ionizing laser pulses. The ob…
Wave localization at the boundary of disordered photonic lattices
A. Szameit, Y. V. Kartashov, P. Zeil +7
We report on the experimental observation of reduced light energy transport and disorder-induced localization close to a boundary of a truncated one-dimensional (1D) disordered pho…
High symmetry versus optical isotropy of a negative index metamaterial
Christoph Menzel, Andrei Andryieuski, Carsten Rockstuhl +4
Optically isotropic metamaterials (MMs) are required for the implementation of subwavelength imaging systems. At first glance one would expect that their design should be based on…
Cryogenic temperatures as a path towards high-Q terahertz metamaterials
Ranjan Singh, Zhen Tian, Jiaguang Han +3
Optical properties of planar thin film metamaterials were measured at room and liquid nitrogen temperatures using terahertz time-domain spectroscopy. The operation of metamaterials…
