Abstract: A glass optical waveguide filament preform is prepared by chemical reaction of vapor ingredients within a glass bait tube. A reactant feed tube extends into one end of the bait tube and terminates just short of the hot zone where reaction occurs. The end of the feed tube traverses the bait tube along with the burner which generates the hot zone. Reactants flow radially from slots in the end of the wall of the feed tube and combine with a flushing gas to form a mixture which flows in a spiral path through the hot zone.

Abstract: An outside chemical vapor deposition apparatus is disclosed for depositing porous glass-forming material onto a target rod to form a cylindrical body, with substantially higher efficiency than could prior apparatus. The apparatus includes two separate burner arrays, one array optimized for depositing the material during an initial stage of the process, when the cylindrical body has a relatively small diameter, and the other array optimized for depositing the material during a later stage of the process, when the cylindrical body has a relatively large diameter. In addition, each burner array can include a plurality of burners, with each burner azimuthally angled relative to the apparatus' air-flow axis, and with adjacent burners angled in opposite directions relative to that axis, to minimize the density gradient within the deposited porous material.

Abstract: Low attenuation, low dispersion of optical waveguides are provided by a process initiating with axial deposition of a high velocity core soot stream impinging on a target at a high angle of incidence relative to the axis of rotation of the target. A core cylinder is built up axially by relative movement between the soot stream and target during deposition, the movement being non-constant in order to maintain a substantially constant diameter with a constant deposition rate. A cladding layer is then built up by deposition of soot radially on the core. Subsequent drying and sintering provides a vitreous preform which may be drawn directly into optical waveguides. Alternatively, the sintered product may be drawn down to smaller rods, which then are covered with further deposited soot cladding to a desired final thickness, and after further drying and sintering may be drawn to optical waveguides.

The tubular starting member is formed of a base glass and at least one dopant, the index of refraction of the tubular starting member being in excess of said base glass. The barrier layer is formed from a base glass and at least one dopant which is maintained substantially constant in the barrier layer.

Abstract: An improved sol-gel process is disclosed for fabricating large monoliths of silica or ceramic material, which are substantially free of cracks. Following formation of the gel, but before the gel is dried, the gel is subjected to a hydrothermal aging treatment, in which it is heated in an autoclave to a temperature of between 100.degree. and 300.degree. C., for a time duration of at least about one hour. This hydrothermal aging treatment causes silica (or ceramic) particles to migrate and fill small pores in the porous gel matrix, such that the average pore size increases and capillary forces encountered in the subsequent drying step are reduced to a point where cracking of the gel is substantially eliminated.

Abstract: A single mode optical waveguide is fabricated in a manner such that the core thereof is subjected to a stress-induced birefringence. A hollow intermediate product is formed by depositing layers of cladding and core glass on the inner surface of a substrate tube. Opposite sides of the intermediate product are heated to cause it to collapse into a solid preform foreproduct having an oblong cross-section. A layer of flame hydrolysis-produced soot having a circular outer surface is deposited on the preform foreproduct and is consolidated to form a dense glass cladding layer thereon. The TCE of the outer cladding layer is different from that of the preform foreproduct on which it is deposited so that when the resultant preform is drawn into a fiber, a stress-induced birefringence exists in the core.
