PROGRESS IN OPTICAL WAVEGUIDE PROCESS AND MATERIALS.

Abstract

The main technologies currently used in the fabrication of optical waveguides are reviewed. Recent key process and material advances which impact fiber performance and/or cost are reported. The processes reviewed include the principal vapor phase oxidation processes as well as the direct-melt approach. Selected recent technical advances which have been made that either capitalize on a process attribute or mark progress toward minimizing or eliminating a process weakness are considered.
