Abstract: The present invention relates to a glass article for use as an optical waveguide fiber and more particularly to an optical waveguide fiber, the core of which is doped with a chalcogenide element to significantly increase the refractive index of the core. The subject of this invention is novel doped silica core compositions wherein a portion of the oxygen in the silica is replaced with either sulfur, selenium or tellurium using plasma enhanced chemical vapor deposition (PECVD). These compositions are designed to have higher refractive indices than silica, low coefficients of expansion, high optical transparency, and appropriate viscosity and softening points to make them ideal candidates for use as optical waveguide fibers.

Abstract: A method for manufacturing an optical article including the steps of providing a substrate tube; forming one or more cladding layers inside the substrate tube, the one or more cladding layers including an innermost cladding layer; forming a concentric fluorine reservoir adjacent to the innermost cladding layer; and forming a core adjacent to the fluorine reservoir and concentric with the one or more outer cladding layers. The fluorine concentration in the fluorine reservoir is higher than the fluorine concentration in either the core or the innermost cladding layer.
