Illuminating the dark corridor in graphene: Polarization dependence of angle-resolved photoemission spectroscopy on graphene

We have used s- and p-polarized synchrotron radiation to image the electronic structure of epitaxial graphene near the (K) over bar point by angle-resolved photoemission spectroscopy (ARPES). Part of the experimental Fermi surface is suppressed due to the ...

Polarization attributes of stimulated Brillouin scattering slow light in fiber

Luc Thévenaz

The polarization-related properties of stimulated Brillouin scattering (SBS) processes in long, randomly birefringent, standard optical fibers are examined. Evolution equations for the pump and signal waves, in the presence of both birefringence and SBS, a ...

Dynamic switching of hole character and single photon polarization using the quantum confined Stark effect in quantum dot-in-dot structures

Elyahou Kapon, Valentina Troncale

The engineering of the three-dimensional (3D) heterostructure potential in GaAs/AlGaAs pyramidal quantum dot-in-dots (DiDs) provides control over the valence band symmetry and hence on the polarization of the emitted photons. We propose a technique for dyn ...

Quantifying electrochemical promotion of induced bipolar Pt particles supported on YSZ

Christos Comninellis, Wolfgang Harbich, Yuehui Li, Michael Hugentobler, Chun Xia

Electrochemical promotion (EP) of CO oxidation is shown for the first time on induced bipolar Pt particles supported on yttria-stabilized zirconia (YSZ). These Pt particles are formed by sputter deposition of high-purity Pt metal followed by sintering. Con ...

Group velocity and energy transport velocity near the band edge of a disordered coupled cavity waveguide: an analytical approach

Romuald Houdré

We develop an analytical approach to theoretically investigate light speed propagation near the band edge of a coupled cavity waveguide in the presence of residual disorder. This approach that is based on a mean field theory allows us to define the domains ...

Analysis of photonic crystal defect modes by maximal symmetrization and reduction

Marc-André Dupertuis, Benjamin Gallinet

We analyze in depth the eigenmodes symmetry of the vectorial electromagnetic wave equation with discrete symmetry, using a recently developed maximal symmetrization and reduction scheme leading to an automatic technique which decomposes every mode into its ...

Dual-polarized and polarization-flexible reflective cells with dynamic phase control

Julien Perruisseau-Carrier

A reflecting cell allowing the dynamic and independent control of the reflection phase of two perpendicular linearly-polarized waves is presented. This capability is useful for the implementation of dual-polarized beam-reconfigurable reflectarrays, as well ...

Coding of spatio-temporal audio spectra using tree-structured directional filterbanks

Martin Vetterli, Francisco Pereira Correia Pinto

We address the problem of integrating directional analysis of sound into the filterbank of a spatial audio coder, with the purpose of processing and coding with some degree of inde- pendence the plane waves traveling in different directions. A plane wave r ...

Unit cells for dual-polarized and polarization-flexible reflectarrays with scanning capabilities

Julien Perruisseau-Carrier

We present the analysis and design of reflecting cells capable of dynamically and independently control the reflection phase of each component of a dual-polarized impinging wave. Such capability is of significant interest for the future implementation of d ...

Vector analysis of stimulated Brillouin scattering amplification in standard single-mode fibers

Luc Thévenaz

The polarization properties of stimulated Brillouin scattering (SBS) amplification or attenuation in standard single-mode fibers are examined through vectorial analysis, simulation and experiment. Vector propagation equations for the signal wave, incorpora ...
