Fabry-Perot Nanocavities in 3D Plasmonic Crystals for Enhanced Biosensing

Extraordinary light transmission effect through Fabry-Perot cavities in 3D plasmonic cystals consisting of two physically separated metallic nanohole and nanodisk array layers is demonstrated. These cavity resonances are highly sensitive to refractive inde ...

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 ...

Some methods of dynamic nuclear polarization for use in metabolic imaging

Fiodar Kurdzesau

It has been suggested already more than 60 years ago to use polarized nuclei in particle scattering experiments1, but only with the discovery of the solid effect dynamic nuclear polarization process2 the realisation of polarized solid targets became possib ...

Infrared investigation of the phonon spectrum in the frustrated spin cluster compound FeTe2O5Cl

László Forró, Helmuth Berger

We present our optical investigations on the frustrated spin cluster compound FeTe2O5Cl, which develops a long-range antiferromagnetic order below 10 K. We measure the optical reflectivity from the far-infrared to the ultraviolet with polarized light. We f ...

Uniaxial strain in graphene by Raman spectroscopy: G peak splitting, Gruneisen parameters, and sample orientation

Nicola Marzari

We uncover the constitutive relation of graphene and probe the physics of its optical phonons by studying its Raman spectrum as a function of uniaxial strain. We find that the doubly degenerate E(2g) optical mode splits in two components: one polarized alo ...

Polarization sensitive silicon photodiodes using nanostructured metallic grids

Olivier Martin, Christian Santschi, Liza Carol Andrea Dunbar

In this paper, we present the design, fabrication, and characterization of wire grid polarizers. These polarizers show high extinction ratios and high transmission with structure dimensions that are compatible with current complementary metal-oxide-semicon ...

Electrochemical evidence of catalysis of oxygen reduction at the polarized liquid–liquid interface by tetraphenylporphyrin monoacid and diacid

Hubert Girault, Bin Su

Cyclic voltammetry is used to study the role of 5,10,15,20-tetraphenyl-21H,23H-porphine (H2TPP) in the reduction of molecular oxygen by decamethylferrocene (DMFc) at the polarized water|1,2-dichloroethane (DCE) interface. It is shown that this rather slow ...

Real-time feedback control of millimeter-wave polarization for LHD

Olivier Sauter, Timothy Goodman, Federico Alberto Alfredo Felici

Electron cyclotron heating (ECH) is widely used in magnetic fusion devices, and the polarization of the injected millimeter-wave beams plays a crucial role in the propagation and absorption of the beam energy by the plasma. This polarization can be adjuste ...

Coulomb correlations of charged excitons in semiconductor quantum dots

Elyahou Kapon, Alok Rudra, Daniel Oberli

The emission pattern of charged excitons in a semiconductor quantum dot (QD) is composed of a quadruplet of linearly polarized lines when a magnetic field is applied in a Voigt configuration. The orientation of the linear polarization of exciton emission i ...

Localized Plasmonic Control of Extraordinary Light Tranmission in Rectangular Coaxial Aperture Arrays at Mid-IR

Hatice Altug, Shyamsunder Erramilli, Xiaoyan Wang

It has been theoretically predicted and experimentally shown that circular coaxial aperture arrays have higher transmissivities with respect to simple circular ones. This observation is mainly attributed to the propagating waveguide modes supported by the ...
