Cette étude porte sur l’utilité de l’Échelle de Communication Verbale de Bordeaux (ECVB,
Darrigrand & Mazaux, 2000), un instrument destiné à évaluer la communication fonctionnelle
d’une personne aphasique dans la vie quotidienne. Cet instrument a été administré à deux reprises
auprès de trois personnes aphasiques présentant différents degrés d’atteinte de la compréhension.
La première étude avait pour objectifs d’identifi er de possibles limites à l’administration de
l’ECVB, ainsi que de...
The radially anisotropic ring-core fiber with cylindrical birefringence is theoretically and numerically investigated as a novel platform for the transmission of vector-vortex beams with unique modal properties. First, we elucidate the parametric conditions where such fiber enables modal substitution in which either the donut-shaped azimuthal TE01 or radial TM01 mode replaces the normal Gaussian-like HE11 mode as the fundamental mode of the waveguide. We also demonstrate that it is possible t...
Heterogeneous integration of materials with a negative thermo-optic coefficient is a
simple and efficient way to compensate the strong detrimental thermal dependence of siliconon-insulator devices. Yet, the list of materials that are both amenable for photonics fabrication
and exhibit a negative TOC is very short and often requires sacrificing loss performance. In this
work, we demonstrate that As₂₀S₈₀ chalcogenide glass thin-films can be used to compensate
silicon thermal effects in micr...
Silicon photonics can be used to increase the versatility of wavelength division multiplexing (WDM). Ultra-dense wavelength division multiplexing (uDWDM) shrinks channel spacing between WDM channels to decrease guard bands and increase spectral efficiency. Microring modulators (MRMs) provide a simple solution for uDWDM transmitters - they require no multiplexer/demultiplexer. When used with comb lasers, MRMs provide extremely compact and low power solutions. The spectral efficiency is limited...
