160W InAlN/GaN HEMTs amplifier at 2 GHz with optimized thermal management

Stéphane Piotrowicz, Olivier Jardel, Jean-Claude Jacquet, D. Lancereau, Raphaël Aubry, Erwan Morvan, Nicolas Sarazin, Jérémy Dufraisse, Charu Dua, Mourad Oualli, Eric Chartier, Marie-Antoinette Di Forte-Poisson, Christophe Gaquière, Sylvain Laurent Delage

We report on the realization and measurements of InAlN/GaN HEMTs on SiC substrate. At device level, load-pull power measurements were performed at 2 GHz on 2.2mm devices in CW mode. An output power of 10.5W (40.2dBm) with a PAE of 53% were reached. Then, an amplifier was realized using 36mm power…

Investigation on the optical gain and threshold current density of Ga1-xInxAs1-y-zNySbz/GaAs strained quantum wells laser

Abdelkader Aissat, Said Nacer, Farid Ykhlef, Jean-Pierre Vilcot

The aim of this work is to exploit the properties of the GaInAsNSb/GaAs alloy compressive highly strain structure. Ga 1-x In x As 1-y-z N y Sb z has been found to be a potentially superior material to GaInAsN for optical fiber communications long wavelength laser (VCSELs) applications. Indeed, this…
