Particles in the core of optical fibers are widely studied to tailor or to improve optical properties. The analysis of nanoparticles embedded in silica-based optical fiber allowed new observations of the evolution of amorphous particles during fiber drawing. Even at the nanoscale, competition between viscous stresses and surface tension on the...

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...
