METHODS AND APPARATUS FOR FORMING A CHLORINE-DOPED OPTICAL WAVEGUIDE PREFORM |
摘要 |
A method of manufacturing an optical waveguide perform includes exposing a soot preform to an atmosphere including a chlorine-containing compound and thereby doping the soot preform with chlorine, wherein the absolute pressure of the atmosphere is greater than about 1.013 x 10<2> kPa. An apparatus for manufacturing an optical waveguide preform using a soot preform includes a furnace defining a chamber adapted to contain the soot preform and including a heating device operable to heat the chamber. A fluid control system is operable to provide an atmosphere including a chlorine-containing compound in the chamber at an absolute pressure of greater than about 1.013 x 10<2> kPa.
