Method of making optical waveguides

A method of making low loss glass optical waveguides, wherein at least one coating of glass soot is deposited by the flame hydrolysis process on a starting member. The starting member is removed from the coating material or glass soot preform leaving an aperture therein, and a tube is secured to one...

Summary:A method of making low loss glass optical waveguides, wherein at least one coating of glass soot is deposited by the flame hydrolysis process on a starting member. The starting member is removed from the coating material or glass soot preform leaving an aperture therein, and a tube is secured to one end of the preform. While the preform is heated to its consolidation termperature, an atmosphere including a drying agent flows from the tube into the aperture and through the porous preform, thereby removing water from the preform while the soot is consolidated to form a dense glass article. The tube can be removed, and the resultant dense glass article can be drawn into an optical waveguide fiber.
