ABSTRACT:
A method is disclosed for making an optical fiber by drawing a preform whose fabrication involves deposition of a glass on a substrate by means of a chemical reaction between gaseous reagents. According to the disclosed method, accurately controlled amounts of a gaseous reagent are produced by flash evaporating a metered flow of a liquid reagent. The disclosed method is of particular interest for the industrial production of optical fibers.
