The development of new applications based on glass doped with nanoparticles is growing in interest during the last years. The structure and properties of Ca-based silicate nanoparticles formed in situ in a silica matrix through a phase separation mechanism were investigated by using Molecular Dynamics simulations and compared to nanoparticles...

An enhancement of the spectroscopic performance of rare-earth-doped silica optical fibers is still required for new photonics applications. An interesting route to tailor their optical behavior consists in embedding rare-earth ions within dielectric nanoparticles in the core of optical fibers. Experimentally, such nanoparticles can be produced...

A Molecular Dynamics study of rare-earth doped Mg-silicate nanoparticles in vitreous silica: from the preform to the fiber. New lasers and amplifiers still require an enhancement of the spectroscopic performance of rare-earth-doped silica optical fibers. In order to tailor their optical behavior, a route of interest consists in embedding...
