Les lasers et amplificateurs à fibres optiques à base de silice dopée d'ions de terres rares (TR) sont développés pour de nombreuses applications. Toutefois, la silice impose des limites à l'amélioration des performances spectroscopiques de nouveaux dispositifs. Pour s'en affranchir, il est proposé d'insérer les ions de TR dans des...

Rare-earth-doped (RE) silica-based optical fiber lasers and amplifiers are developed for numerous applications. However, silica glass has certain characteristics (high phonon energy, low RE solubility, …) which may be detrimental for the luminescence properties of RE. To overcome this issue, the incorporation of RE in nanoparticles is...

Rare-earth-doped oxide nanoparticles in the core of silica optical fibers are becoming well studied as they yield enhanced and tailorable spectroscopic and optical properties. In this paper, the evolution of particle morphology , induced by the drawing step, is studied. Indeed, during the fiber draw process, the glass flows and particles can...
