Bloch Surface Waves Based Platform for Integrated Optics

Hans Peter Herzig, Elsie Barakat, Richa Dubey

A dielectric multilayer platform sustaining Bloch surface waves is investigated for planar integrated optics. We study the optical properties of high refractive index material (TiO2) and obtain propagation lengths in the range of millimeters. ...

Volume refractometry of liquids using stable optofluidic Fabry-Perot resonator with curved surfaces

Maurine Malak Karam Awadallah

This work reports a simple, miniaturized optical sensing module for liquid refractometry. It is based on a stable Fabry-Perot resonator consisting of two silicon cylindrical mirrors with a cylindrical lens in the core. The lens is formed by a capillary tub ...

Extreme Ultraviolet Transient Grating Measurement of Insulator-Metal Transition Dynamics in VO2

Jakob Grilj

We demonstrate spectrally resolved transient grating (TG) spectroscopy in the extreme ultraviolet (EUV) near the M-edge of vanadium dioxide. Time-dependent and broadband EUV-TG measurements separate the index of refraction change due to the insulator to me ...

On the Design of Highly Luminescent Lanthanide Complexes

Jean-Claude Bünzli

Presently, phosphors and luminescent materials for lighting, telecommunications, displays, security inks and marking, as well as for probes in biosciences represent one third of the total value of the lanthanides used worldwide. If optical glasses and lase ...

Nanocrystalline Low-Refractive Magnesium Fluoride Films Deposited by Reactive Magnetron Sputtering: Optical and Structural Properties

Jean-Louis Scartezzini, Paul Muralt, Silviu Cosmin Sandu, Stefan Mertin

In this work, we study MgF2 thin-film synthesis by reactive pulsed DC magnetron sputtering from a metallic magnesium target in a gas mixture of argon, oxygen, and carbon tetrafluoride (CF4). Nanocrystalline films on silicon and glass substrates with excell ...

Mid-infrared plasmonic biosensing with graphene

Hatice Altug, Dordaneh Etezadi, Daniel Rodrigo Lopez, Odeta Limaj

Infrared spectroscopy is the technique of choice for chemical identification of biomolecules through their vibrational fingerprints. However, infrared light interacts poorly with nanometric-size molecules. We exploit the unique electro-optical properties o ...

Ancient administrative handwritten documents: X-ray analysis and imaging

Giorgio Margaritondo, Frédéric Kaplan, Fauzia Albertin

Handwritten characters in administrative antique documents from three centuries have been detected using different synchrotron X-ray imaging techniques. Heavy elements in ancient inks, present even for everyday administrative manuscripts as shown by X-ray ...

Method of producing a reflective or refractive surface

Mark Pauly

A method and apparatus for producing a reflective or refractive surface that reflects or refracts light shined thereon and reproduces on a screen a desired greyscale intensity image on which the reflective or refractive surface is based and a corresponding ...

Manipulation of electron flow using near-zero index semiconductor metamaterials

Romain Christophe Rémy Fleury

We study the possibility of controlling the propagation of ballistic electrons using an electronic metamaterial with zero quantum index of refraction. This is obtained by tailoring the band structure of a semiconductor superlattice to exhibit a Dirac cone ...
