PRESSED, MULTILAYERED SILICA SOOT PREFORMS FOR THE MANUFACTURE OF SINGLE SINTER STEP, COMPLEX REFRACTIVE INDEX PROFILE OPTICAL FIBER

摘要

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.
