Abstract

Official abstract text for this publication.

Manufacturing an optical fiber by using an outside vapor deposition technique for making a substrate, applying one or more layers to the substrate using a radial pressing technique to form a soot blank, sintering the soot blank in the presence of a gaseous refractive index-modifying dopant, and drawing the sintered soot blank, provides a more efficient and cost effective process for generating complex refractive index profiles.

First claim

Opening claim text (preview).

What is claimed is: 1. A process for use in the manufacture of an optical fiber, comprising: preparing an inner cladding layer of silica soot which surrounds a core using an outside vapor deposition technique; pressing at least one layer of silica powder over the inner cladding layer to obtain a monolithic soot blank, wherein the at least one layer of silica powder has a surface area that is different from the inner cladding layer; and sintering the monolithic soot blank in th…
