Abstract
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 soot coating is heated to its consolidation temperature in an atmosphere containing helium and an amount of chlorine that is effective to substantially remove the water from the glass soot while the soot is being consolidated to form a dense glass layer. The starting member is removed unless it is to form a part of the optical waveguide. The resultant structure, including the dense glass body, is then drawn into a waveguide fiber.
