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.
Claims22
A method for forming an optical fiber preform comprising:
- forming silica particles from a silica precursor;
- forming germania particles from a germania precursor;
- depositing the silica particles and the germania particles on a substrate to form a soot preform, the substrate having a temperature less than 1,250° C.;
- and
- wherein at least one of the silica precursor and germania precursor is an organic precursor.
