Time- and angle-resolved photoemission spectroscopy of solids in the extreme ultraviolet at 500 kHz repetition rate

Time- and angle-resolved photoemission spectroscopy (trARPES) employing a 500 kHz extreme-ultraviolet light source operating at 21.7 eV probe photon energy is reported. Based on a high-power ytterbium laser, optical parametric chirped pulse amplification, ...

Pancreatic beta cell based optical biosensor and system for continuous glucose monitoring

Catherine Dehollain, Umberto De Marchi, Bakul Jitendra Vinchhi, Nicolas Bouche, Christophe Boss, Ninad Dilip Agashe

A bio-electronics system that measures cytosolic [Ca2+] in vitro in the INS-1E pancreatic beta-cells using a 430 nm excitation light with the excitation wavelength of the probe being at 435 nm was successfully implemented and tested. We transfected the INS ...

JPEG Pleno: Providing representation interoperability for holographic applications and devices

Touradj Ebrahimi

Guaranteeing interoperability between devices and applications is the core role of standards organizations. Since its first JPEG standard in 1992, the Joint Photographic Experts Group (JPEG) has published several image coding standards that have been succe ...

Experimental demonstration of ray-rotation sheets

Toralf Scharf

We have built microstructured sheets that rotate, on transmission, the direction of light rays by an arbitrary, but fixed, angle around the sheet normal. These ray-rotation sheets comprise two pairs of confocal lenticular arrays. In addition to rotating th ...

Light Confinement and Nonlinear Light-Matter Interaction in Semiconductor Photonic Crystal Cavities

Mohamed Sabry Abdel-Aliem Mohamed

The ability to control and manipulate light is a fundamental aspect that is at the very core of the development of integrated photonic circuits. It is desirable to achieve such control down to a scale that is comparable to or smaller than the wavelength of ...

Sampling the Multiple Facets of Light

Gilles Baechler

The theme of this thesis revolves around three important manifestations of light, namely its corpuscular, wave and electromagnetic nature. Our goal is to exploit these principles to analyze, design and build imaging modalities by developing new signal proc ...

Reactive species monitoring and their contribution for removal of textile effluent with photocatalysis under UV and visible lights: Dynamics and mechanism

Sami Rtimi

In this study, the photocatalytic activities were investigated for the treatment of Reactive Green 12 (RG 12) solution under UV and visible irradiation using Cu doped TiO2, and TiO2 impregnated on (1) cellulose and (2) UV-C activated polyester catalysts. T ...

Type II solutions Type II blow up solutions with optimal stability properties for the critical focussing nonlinear wave equation on $\R^{3+1}$

Joachim Krieger, Stefano Francesco Burzio

We show that the finite time type II blow up solutions for the energy critical nonlinear wave equation [ \Box u = -u^5 ] on

\R^{3+1}

constructed in \cite{KST}, \cite{KS1} are stable along a co-dimension one Lipschitz manifold of data perturbations in a ...

Distributed forward Brillouin sensor based on local light phase recovery

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhisheng Yang, Desmond Chow Ming Chia

The distributed fibre sensing technology based on backward stimulated Brillouin scattering (BSBS) is experiencing a rapid development. However, all reported implementations of distributed Brillouin fibre sensors until today are restricted to detecting phys ...

Geometry-Consistent Light Field Super-Resolution via Graph-Based Regularization

Pascal Frossard, Mattia Rossi

Light field cameras capture the 3D information in a scene with a single exposure. This special feature makes light field cameras very appealing for a variety of applications: from post-capture refocus, to depth estimation and image-based rendering. However ...
