    Abstract: An apparatus for producing the glass soot used in the formation of optical fiber includes a burner with an internal atomizer. The atomizer includes an outer tube having a nozzle at an end thereof, and an inner tube located within the outer tube and having a closed end restricting fluid flow therethrough and defining a cylindrical sidewall having radially extending apertures spaced there along. The outer tube receives the glass-forming mixture in liquid form and the inner tube receives an atomizing gas which flows through the apertures in the sidewall of the inner tube and atomizes the glass-forming mixture as the glass-forming mixture travels through the outer tube.

    Abstract: A method is provided for making an optical fiber by melting and cladding a multi-component core glass without adding the contamination that is normally associated with these processes. As an initial step, a pure multi-component glass is melted in a high purity silica crucible. The temperature of the glass in the crucible and the temperature of the orifice thereof are controlled so that a cane of glass is drawn from the bottom of the crucible. This cane of glass is fed into a silica or borosilicate tube which is being drawn into a fiber. This results in an optical fiber in which the multi-component glass forms the core while the tube forms the cladding.

    Abstract: There is disclosed a method and apparatus for providing optically pure water-free fused silica blanks, tubing and crucibles for use in forming optical waveguides, lenses, prisms, filters, and high temperature lamp envelopes, in which soot is deposited on a high purity graphite bait or refractory low expansion glass, glass-ceramic or suitable crystalline ceramic bait by a flame hydrolysis method in which the burner is located close to the bait. This results in an exceptionally dense soot preform. The preform is later sintered in an inert dry atmosphere by slowly inserting the soot covered bait into a furnace in such a manner that entrapped gas is forced from the fused silica during the slow insertion into the furnace maintained at a temperature above 1,400*C. The formation of bubbles within the fused silica is prevented because of the inert atmosphere and because the gases in the preform escape through the unsintered portions of the preform, thereby providing a crucible or blank of fused silica of exceptionally high optical quality.
