ABSTRACT:
A method of forming a preform or blank for an optical filament, the preform itself, and resulting optical filament is disclosed. A hollow cylindrical substrate is provided within which is disposed a burner having a substantially radial flame. Reactants are flowed into the hollow cylindrical substrate in the annular space between the inner surface of said substrate and the exterior of said burner. A hot zone is established within the interior of said substrate in the vicinity of said radial flame so that the reactants are reacted to produce a suspension of particulate material. The burner is traversed substantially along the longitudinal axis of the substrate whereby the hot zone is caused to move along the length of said substrate. A portion of the particulate material formed within the hot zone travels downstream where at least a portion thereof comes to rest on the inner surface of the substrate to subsequently form a continuous glassy deposit thereon. A second burner at the exterior of said substrate may be employed to provide a source of heat from the exterior adjacent the hot zone. Also, a shield may be provided surrounding the burner within said hollow substrate and a stream of gas flowed within said shield around the burner to confine the flow of particulate material to an annular channel adjacent to the inner surface of the substrate increasing deposition efficiency of the particulate material on the inside surface of the substrate.
