Rare-earth (RE) containing glasses are known to be good candidate materials for devices such as optical fiber amplifiers, upconversion lasers and glass lasers. In such materials, strong changes in the luminescent properties can be induced by changes in the distribution and local environment of the RE ions. The investigation of the local...
The success of silica-based optical fibers are many: transmission fibers and fiber amplifiers for telecommunications, high-power fiber lasers or sensors. These key applications rely on the qualities of silica glass: mechanical and chemical stability, high optical damage threshold, low cost, etc. New lasers and amplifiers based on rare-earth...
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...
