Erbium- and Magnesium-codoped Silica-Based Transparent Glass Ceramic Core Fiber Made by FCVD and Flash Vaporization
Résumé
A fiber made by Furnace CVD was codoped with Erbium and Magnesium using a Flash Vaporization System for the first time. The fiber core is spontaneously formed as a Transparent Glass Ceramic (TGC). Due to the small nanoparticle size (<50 nm) and high volumetric density (10 20 ~10 21 m-3), the optical loss due to scattering is as low as < 0,6 dB/m. Erbium ions are highly concentrated within phase-separated nanoparticles. We study the absorption and emission properties of Erbium around 1.55 µm in this TGC-core fiber.
