New Fluoride Glasses for the Preparation of Infrared Optical Fibers
Abstract
New zirconium-free fluoride glasses are investigated for I.R. optical fibers operating up to 5-5.5 um. A five-component glass having the composition in molar percent fluoride Ba30In30Zn20Y10Th10 has been optimized for rods and preforms preparation. F/C1 substitution as well as Na addition allow small variations in the refractive index. Two attempts on rods fibering were positive and demonstrated the possibility of obtaining BIZYT optical fibers without significant crystallization. Purification of indium and Yb based materials has been undertaken. Keywords: Fluoride glasses, Indium-based, Zirconium, Optical fibers, Viscosity, Purification.
