New Fluoride Glasses for the Preparation of Infrared Optical Fibers.

Abstract

New indium-based fluoride glasses called BIZYT, resistant to devitrification, have been investigated in order to measure their chemical durability versus humidity. The corrosion mechanism has been studied and the molar absorption coefficient of the OH parasitic peak has been evaluated. Also the evolution of the refractive index and the material dispersion versus lambda have been investigated. In order to design a core-clad structure, the variation of refractive index with chemical composition has been measured for LiF and PbF2 containing glasses. Keywords: Fluoride glasses, Indium, Optimization, Devitrification, IR Transmission, Refractive index, Material dispersion, Corrosion water, OH absorption coefficient.
