Optical fibers are the basis for applications that have grown considerably in recent years (telecommunications, sensors, fiber lasers, etc). To fulfill the characteristics required for these applications, optical fibers are obtained by drawing high-purity silica-based preforms. This drawing step is usually assumed to be a homothetic...

Nanoparticles in the core of optical fibres are widely studied due to the opportunity they give to tailor spectroscopic properties. Such fibres are usually obtained by drawing at high temperature a preform containing nanoparticles. This study focuses on the effect of the fibre drawing on nanoparticles. We fabricated an MCVD optical preform by...

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...
