Abstract: There is initially formed a draw blank having diametrically opposed longitudinal apertures in the cladding glass parallel to the core glass region. The draw blank is drawn into a fiber under such conditions that the apertures close as the fiber is being drawn. The flow of surrounding glass, including the core glass region, toward the collapsing apertures, causes the core to assume an elliptical shape. The apertures are of such cross-sectional area and spacing from the core that the core develops the desired aspect ratio.

Abstract: A method is provided of forming an elongated glass article, comprising providing a tubular glass handle having a mandrel protruding from one end thereof, rotating the combination of mandrel and tube, and directing toward the rotating mandrel and an end portion of the tube a stream of glass particles comprising SiO 2 doped with at least 15 wt. % B 2 O 3 while reciprocating said mandrel and tube with respect to said stream to build up a porous glass coating. The mandrel is then removed from the porous glass coating and tube to form an assembly of handle and tubular porous preform. The porous preform is heated to consolidate it to a dense glass preform having an axial aperture, and to fuse the dense glass preform to the handle. NF 3 is flowed through the aperture while maintaining the temperature of the consolidated preform above 600°C but below that temperature which would cause the substantial elongation of the blank.

Abstract: Disclosed is a method of making a polarization retaining single-mode optical fiber. There is initially formed a draw blank having diametrically opposed longitudinal apertures in the cladding glass parallel to the core glass region. The draw blank is drawn into a fiber under such conditions that the apertures close as the fiber is being drawn. The flow of surrounding glass, including the core glass region, toward the collapsing apertures, causes the core to assume an elliptical shape. The apertures are of such cross-sectional area and spacing from the core that the core develops the desired aspect ratio.
