Growth of rare-earth doped oxyde nanoparticles in silica fibers", 9th Symposium "SiO2: Advanced Dielectrics and Related Devices

Rare earth (RE) doped silica-based optical fibers with transparent glass ceramic (TGC) core was fabricated through the well-known modified chemical vapor deposition (MCVD) process without going through the commonly used stage of post-ceramming. The main characteristics of the RE-doped oxyde nanoparticles, their density and mean diameter in the fibers are dictated by various parameters discussed during this presentation. Low scattering losses induced by nano-scale particles and alteration of the spectroscopic properties of the erbium ions were observed. These initial studies should be useful in incorporating new doped materials in order to realize active optical fibers for constructing lasers and amplifiers.
