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...

Since the ground-breaking discovery done in the 1960s by Charles K. Kao, the perfect glass, i.e. the most transparent glass, drives the development of optical fibers. Meanwhile, to overcome some limitations imposed by the silica glass, one recent strategy consists of embedding nanoparticles in the core of the optical fiber, leading to light...

Since the 1970s, the development of optical fibers has been relying on the quest for the perfect silica glass, i.e. the most transparent one. Meanwhile, silica glass introduces limitations (high phonon energy, low rare-earth ions solubility, etc.) which could be detrimental for new applications. To overcome those drawbacks, a recent strategy...
