Flash vaporizer system for delivering reactants for flame hydrolysis deposition and method of forming optical waveguide preforms therewith.

摘要

A system for delivering a liquid reactant (2) at high flow rates to an oxidation/flame hydrolysis glass soot deposition site (10). A first liquid only reactant (2) is delivered (7,4) to a vaporization chamber (1) to form a thin film and mixed with oxygen (20) after vaporization. Additional vaporized reactants (30) are thereafter mixed (11) with the vaporized first liquid (1) prior to delivery to an oxidation/flame hydrolysis burner (10) to form a glass soot outer cladding layer on a soot preform. The soot preform is subsequently fused to form a high quality glass blank for drawing into optical fiber. <IMAGE>
