High performance wafer-fused semiconductor disk lasers emitting in the 1300 nm waveband

Elyahou Kapon, Nicolas Volet, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman

We report for the first time on the performance of 1300 nm waveband semiconductor disc lasers (SDLs) with wafer fused gain mirrors that implement intracavity diamond and flip-chip heat dissipation schemes based on the same gain material. With a new type of ...

Compressed Quantitative MRI: Bloch Response Recovery through iterated projection

Pierre Vandergheynst, Yves Wiaux, Gilles Puy

Inspired by the recently proposed Magnetic Resonance Fin- gerprinting technique, we develop a principled compressed sensing framework for quantitative MRI. The three key com- ponents are: a random pulse excitation sequence following the MRF technique; a ra ...

Extending the sensing range of Brillouin optical time-domain analysis up to 325 km combining four optical repeaters

Luc Thévenaz, Sang Hoon Chin, Flavien Gyger

A novel scheme is proposed to extend the sensing range of Brillouin optical time-domain analyzers (BOTDA). Specially-designed erbium doped fiber amplifier (EDFA) repeaters are located every 65km fiber along the sensing cable to achieve a total sensing leng ...

Measurements of local chemistry and structure in Ni(O)-YSZ composites during reduction using energy-filtered environmental TEM

Jan Van Herle, Cécile Hébert, Aïcha Hessler-Wyser, Quentin Thomas Jeangros

Energy-filtered transmission electron microscopy images are acquired during the reduction of a NiO-YSZ composite in H-2 up to 600 degrees C. Temperature-resolved quantitative information about both chemistry and structure is extracted with nm spatial resol ...

Imaging of high-Q cavity optical modes by electron energy-loss microscopy

Romuald Houdré, Cécile Hébert, Marco Cantoni, Duncan Thomas Lindsay Alexander, Nicolas Le Thomas

We show a technique that images the intensity distribution and local state of polarization of the optical field of high-quality factor optical modes confined in dielectric planar photonic crystal nanocavities. Based on energy-loss spectroscopy of swift ele ...

Enlightening G-protein-coupled receptors on the plasma membrane using super-resolution photoactivated localization microscopy

Aleksandra Radenovic, Paolo Annibale, Marco Scarselli

The possibility to visualize and image the arrangement of proteins within the cell at the molecular level has always been an attraction for scientists in biological research. In particular, for signalling molecules such as GPCRs (G-protein-coupled receptor ...

Experimental and theoretical study of the Gouy phase anomaly of light in the focus of microlenses

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim, Ali Naqavi

We report on the Gouy phase anomaly of light in the focus of cylindrical and spherical microlenses. The prime subject of our study concerns a discussion of how the very small size of microlenses affects the phase properties of light in their foci. We put e ...

Interpolating point spread function anisotropy

Frédéric Courbin, Georges Meylan, Marc Gentile

Planned wide-field weak lensing surveys are expected to reduce the statistical errors on the shear field to unprecedented levels. In contrast, systematic errors like those induced by the convolution with the point spread function (PSF) will not benefit fro ...

Influence of reflecting walls on edge diffraction simulation in geometrical acoustics

Dirk Schröder

Edge diffraction can be introduced into Geometrical Acoustics mainly by three models: detour-based, energetic and wave-based diffraction models. In the past, we thoroughly compared Maekawa's detour law, the uncertainty relation based diffraction method and ...
