Abstract: Filament in tube and stick in tube processes of forming optical fiber are described. A solid or monolithic core feedstock (110) is disposed in a hollow cladding structure (112) to form a loosely filled cladding structure. The filled cladding structure is heated to a draw temperature approximately equal to the softening temperature of the cladding structure. The feedstock (110) melts and fills the heated portion of the cladding structure forming a filled core which can then be drawn into optical fiber or to an optical can which can then be further overclad consolidated and drawn into fiber. Feedstock (110) and cladding structures (112) having widely varying coefficients of expansion may be employed. The resulting fiber can be readily designed to be fused to existing installed fibers.

Abstract: Disclosed is a method of forming a doped glass article. Heated glass particles are deposited on a mandrel where they adhere together to form a porous glass preform having interconnective pores. The mandrel is removed to form a tubular preform having an axial aperture. The preform is suspended in a consolidation furnace by a gas conducting handle having a dopant containing chamber. As the handle and preform are heated, there is flowed through the chamber a gas that reacts with the heated dopant to form a reactant gas that flows into the aperture and into pores, whereby a dopant is incorporated into the porous glass preform. The doped preform is heat treated to consolidate it into an elongated non-porous glass body containing the dopant. The glass body can be provided with cladding glass and drawn into an optical fiber.

Abstract: A method of producing silica glass, which comprises:

(a) a step of diffusing a dopant into pores of porous glass by bringing the dopant in a gas phase into contact with the porous glass until the dopant reaches an adsorption equilibrium amount,
(b) a step of partially removing the diffused dopant by holding the porous glass in an atmosphere maintaining a partial pressure of the dopant at a lower level than that of an equilibrium adsorption pressure of the dopant in the above diffusion step (a) to lower the dopant concentration in the vicinity of the porous glass surface portion,
(c) a step of fixing the dopant within the pores of the porous glass, and
(d) a step of firing the porous glass to render it nonporous.
