Large-scale sub-100 nm compound plasmonic grating arrays to control the interaction between localized and propagating plasmons

Olivier Martin, Thomas Gerd Siegfried, Arash Farhang

Compound plasmonic resonances arise due to the interaction between discrete and continuous metallic nanostructures. Such combined nanostructures provide a versatility and tunability beyond that of most other metallic nanostructures. In order to observe suc ...

Microwave photonics filtering technique for interrogating long weak fiber Bragg grating sensors

Luc Thévenaz

A system to interrogate photonic sensors based on long weak fiber Bragg gratings (FBGs) is presented and experimentally demonstrated, dedicated to measure the precise location of several spot events. The principle of operation is based on a technique used ...

Probing inhomogeneous composition in core/shell nanowires by Raman spectroscopy

Anna Fontcuberta i Morral, Federico Matteini, Esther Alarcon Llado, Martin Heiss, Eleonora Russo, Sonia Conesa Boj, Francesca Amaduzzi

Due to its non-destructive and its micro-spatial resolution, Raman spectroscopy is a powerful tool for a rapid structural and compositional characterization of nanoscale materials. Here, by combining the compositional dependence of the Raman peaks with the ...

Nanostructuring and lattice dynamics of materials by femtosecond lasers

Ahmad Odeh

Physically, the colour of an object is a complex result of its intrinsic surface properties, its transmission properties and its emission properties, all of which contribute to the mix of wavelengths in the light leaving the surface of the object. Structur ...

Crystal Structure and Solution Species of Ce(III) and Ce(IV) Formates: From Mononuclear to Hexanuclear Complexes

Philip Pattison, Stephan Weiss

Cerium(III) and cerium(IV) both form formate complexes. However, the species in aqueous solution and the solid-state structures are surprisingly different. Ce(III) shows only mononuclear complexes in aqueous solution, whereas Ce(IV) forms a stable hexanucl ...

Structural mechanism of cytosolic DNA sensing by cGAS

Andrea Ablasser

Cytosolic DNA arising from intracellular bacterial or viral infections is a powerful pathogen-associated molecular pattern (PAMP) that leads to innate immune host defence by the production of type I interferon and inflammatory cytokines. Recognition of cyt ...

Juxtaposed Color Halftoning Relying on Discrete Lines

Roger Hersch, Vahid Babaei

Most halftoning techniques allow screen dots to overlap. They rely on the assumption that the inks are transparent, i.e. the inks do not scatter a significant portion of the light back to the air. However, many special effect inks such as metallic inks, ir ...

Self-sensing dielectric elastomer actuators in closed-loop operation

Herbert Shea, Samuel Rosset

Because of their large output strain, dielectric elastomer actuators (DEAs) have been proposed for tunable optics applications such as tunable gratings. However, the inherent viscoelastic drift of these actuators is an important drawback and closed-loop op ...

Resonant absorption enhancement in solar cells with periodically textured interfaces

Christophe Ballif, Franz-Josef Haug, Karin Söderström

We use a 1D grating back reflector to study the mechanism of light trapping in solar cells. Experimental results of a full solar cell on a sinusoidal back reflector are compared to a theoretical model using an expansion into grating modes and the Rayleigh ...
