Normally Incident Wave Propagation across One Joint Set with Virtual Wave Source Method

This paper presents an analytical study on normally incident wave propagation across a joint set. Combined with the displacement discontinuity method (DDM), the virtual wave source method (VWSM) is adopted to take account of multiple wave reflections among ...

Re-Use of c-Si Solar Cells from Failed PV Modules

Christophe Ballif, Hengyu Li, Laure-Emmanuelle Perret Aebi, Yun Luo

The recycling or re-use of failed c-Si PV modules could be a significant concern in the near future. The existing approaches for cell recovery can be improved both environmentally and economically friendly. Here we propose a novel double encapsulation modu ...

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 ...

One-dimensional exciton luminescence induced by extended defects in nonpolar GaN/(Al,Ga)N quantum wells

Nicolas Grandjean, Benoît Marie Joseph Deveaud, Raphaël Butté, Jacques Levrat, Pierre Stadelmann, Jean-Daniel Ganière, Denis Martin, Pierre Michel Corfdir, Tiankai Zhu, Yadira Arroyo Rojas Dasilva

In this study, we present the optical properties of nonpolar GaN/(Al,Ga)N single quantum wells (QWs) grown on either a- or m-plane GaN templates for Al contents set below 15%. In order to reduce the density of extended defects, the templates have been proc ...

Metallic Optical Nanostructures: a Solution for Planar Integrated Sensors on Waveguides

Hans Peter Herzig, Qing Tan, Armando Cosentino

We study the optical properties of two different metallic nanostructure arrays for lable-free sensing applications. The sensors are optimized to detect refractive index (RI) variations. The optical interaction between light and analyte is enhanced by field ...

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 ...

Ink-dependent n-factors for the Yule-Nielsen modified spectral Neugebauer model

Roger Hersch, Romain Rossier

Different inks may have different mechanical and/or optical properties. Existing Yule-Nielsen modified Neugebauer spectral prediction models assume however that the inks forming a color halftone behave similarly, i.e. that a single n-factor can model the l ...

Determination of local optical properties of the rat barrel cortex during neural activation: Monte-Carlo approach to light propagation

Pierre Magistretti, Christian Depeursinge, Pierre Marquet, Stéphane Chamot, Elena Migacheva

Spatially-spectrally-resolved reflectance measurements allow in vivo measuring the optical coefficients of absorption and scattering within the cortical tissue. This method, if applied to neural tissue during enhanced activity, could allow a straightforwar ...

Solving surface plasmon resonances and near field in metallic nanostructures: Green's matrix method and its applications

Olivier Martin

With the development of nanotechnology, many new optical phenomena in nanoscale have been demonstrated. Through the coupling of optical waves and collective oscillations of free electrons in metallic nanostructures, surface plasmon polaritons can be excite ...
