ORGANIC GERMANIA AND SILICA SOURCES FOR MAKING OPTICAL FIBER PREFORMS

Abstract:

Disclosed herein are methods for forming an optical fiber preform using organic silica and germania precursors. The method includes depositing soot composed of germanium dioxide and silica on a substrate, removing the substrate, conducting a dehydration step and one or more heating steps under an oxygen-containing atmosphere to form the preform. Also disclosed are optical fibers drawn from the preforms produced herein.
