PRESSED, MULTI-LAYER SILICON Dioxide DISEASES FOR THE PREPARATION OF OPTICAL FIBER WITH COMPLEX REFINING INDEX PROFILE IN A SIMPLE SINTERING STEP

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.
