Fast polarizers installation for ECRH and ECE in TCV

Timothy Goodman, Federico Alberto Alfredo Felici, Laurie Porte

We report on the installation of fast polarizers for ECRH injection and ECE diagnostics, in the TCV tokamak. The main goal is to change the polarization during a plasma shot and react to changing conditions such as: plasma current and position, ECRH inject ...

A 6.5 - 50 GHz battery-powered compact rotary joint for polarization ellipticity measurements

Jean-François Zürcher

A simple, efficient, and compact rotary joint has been designed, realized, and measured. It has been used intensively to perform polarization ellipticity measurements on various circularly polarized antennas (e.g., helical antennas and circularly polarized ...

Brillouin Echoes for Advanced Distributed Sensing in Optical Fibres

Stella Foaleng Mafang

Brillouin scattering is particularly efficient and attractive for the implementation of strain and temperature distributed sensing in optical fibres. Recently a trend has been observed that modern advanced applications require a substantial step towards be ...

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 ...

Integrated nanoplasmonic-nanofluidic biosensors with targeted delivery of analytes

Hatice Altug, Min Huang

Performances of the biosensors are often limited by the depletion zones created around the sensing area which impede the effective analyte transport. To overcome this limitation, we propose and demonstrate a nanoplasmonic-nanofluidic sensor enabling target ...

The stress-assisted enhancement of piezoelectric properties due to mechanically incompatible domain structures in BaTiO3

Nava Setter, Alexander Tagantsev, Dragan Damjanovic, Tomas Sluka, Enrico Colla, Mahamudu Mtebwa

The piezoelectric properties of tetragonal BaTiO3 (BTO) crystals with a high density of 90° twin domain boundaries were experimentally investigated by Wada and Tsurumi (2004 Br. Ceram. Trans. 103 93). These crystals with engineered dense domain structures ...

Design Principles for Optoelectronic Applications of Extraordinary Light Transmission Effect in Plasmonics Nanoapertures

Hatice Altug

The extraordinary light transmission effect (EOT) through sub-wavelength nanoapertures in opaque metal films has lead to observation of a wide variety of exciting new optical phenomena. This remarkable effect is generally related to the interaction of the ...

Pinning and Depinning of the Polarization of Exciton-Polariton Condensates at Room Temperature

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Eric Feltin, Jacques Levrat, Marlene Glauser

A room temperature polariton condensate realized in a microcavity with embedded GaN quantum wells emits linearly polarized light at threshold with the plane of polarization pinned to one of the crystallographic axes. With increasing pumping power, a depinn ...

An Optofluidic Nanoplasmonic Biosensor for Direct Detection of Live Viruses from Biological Media

Hatice Altug, Min Huang

Fast and sensitive virus detection techniques which can be rapidly deployed at multiple sites are essential to prevent and control future epidemics and bioterrorism threats In this Letter we demonstrate a label free optofluidic nanoplasmonic sensor that ca ...
