摘要： A liquid cooling method and apparatus for rapid cooling of a hot glass fiber. In FIG. 1, an open ended liquid coolant container (12) is provided at its lower end with an inverted funnel surface (34). A vertically running, hot glass fiber (42) of indefinite length is continuously drawn through the container, as the container continuously receives a coolant liquid at its upper open end (30). The liquid continuously drains from the container lower open end (32) by flowing along flow surface (36) of the inverted funnel (34), downwardly and away from the glass fiber (42). The temperature of the fiber relative to the temperature of the coolant liquid is such that a vapor barrier surrounding the hot fiber is formed due to boiling of the liquid in a zone surrounding the fiber. This vapor zone facilitates diversion of the liquid (change in direction of flow) from the vertical to an angle thereto, along the inverted funnel surface. The substantially cooled hot glass fiber passes out of the container lower end for further processing, such as coating the fiber. The method and apparatus yields cooled glass fiber not wetted by the coolant liquid.

摘要： A precision burner for oxidizing halide-free, silicon-containing compounds, such as, octamethylcyclotetrasiloxane (OMCTS), is provided. The burner includes a subassembly (13) which can be precisely mounted on a burner mounting block (107) through the use of an alignment stub (158), a raised face (162) on the burner mounting block (107), and a recess (160) in the back of the subassembly (13). The burner's face includes four concentric gas-emitting regions: a first central region (36, 90) from which exits a mixture of OMCTS and O.sub.2, a second innershield region (38, 92) from which exits N.sub.2, a third outershield region (40, 42, 94, 96) from which exits O.sub.2, and a fourth premix region (44, 98) from which exits a mixture of CH.sub.4 and O.sub.2. The burner provides more efficient utilization of halide-free, silicon-containing raw materials than prior burners.

摘要： The present invention is directed to methods of producing soot used in the manufacture of optical waveguides. Both non-aqueous liquid reactants and aqueous solutions containing one or more salts are delivered through an atomizing burner assembly to form a homogenous soot stream containing the oxides of the selected elements contained within the non-aqueous liquid reactant and the aqueous solution. The resulting multi-component soot is collected by conventional methods to form preforms used in the manufacture of optical waveguide fibers. Preforms formed by the methods are also disclosed.

摘要： A vaporizer (film evaporator) (13) for halide-free, silicon-containing liquid reactants used in producing preforms is provided. The vaporizer includes a plurality of packed-bed columns (22) surrounding a central tube (24). A mixture of liquid reactant, e.g., octamethyl-cyclotetrasiloxane, and gas, e.g., oxygen, is sprayed onto the top surfaces (54) of the columns (22) by a set of spray nozzles (32). The liquid reactant and the gas flow downward together through the columns and are heated by hot oil (28) which flows around the columns' walls (50). The liquid reactant evaporates into the gas until the dew point temperature is reached, at which point all of the liquid reactant will have been converted into vapor. The vapor/gas mixture exits the bottom surfaces 56 of columns (22), where its direction of flow changes from downward to upward. This change in flow direction separates higher molecular weight species (46) from the vapor/gas mixture. The vapor/gas mixture leaves the vaporizer (13) through central tube (24) and is supplied to soot-producing burners (20) where it is used to produce preforms.

摘要： Disclosed are refractive index profiles for total dispersion compensating optical waveguide fibers for use in high data rate, long length telecommunications systems. The optical waveguide fibers in accord with the invention provide substantially equal compensation of total dispersion over a range of wavelengths, thus facilitating wavelength division multiplexed systems. Also disclosed are spans of optical waveguide fiber that include a length of transmission fiber together with a length of the compensating fiber. The spans are joined end to end in series arrangement to form the optical waveguide fiber part of a telecommunication system.

摘要： Disclosed is a dispersion compensating waveguide fiber suitable for use in high data rate, high light power telecommunications systems of intermediate length. The refractive index profile of the compensation fiber is segmented. The segment relative refractive indexes and radii are chosen to provide negative total dispersion and negative total dispersion slope over an extended wavelength range. The index profile design is flexible enough to provide compensated links having total dispersion that is positive, negative, or zero, while maintaining appropriate total dispersion slope compensation. In addition, the waveguide fiber of the invention may be cabled or otherwise buffered prior to its use in a communications system.

摘要： A fiber optic coupler is formed by providing a glass tube having a longitudinal aperture extending therethrough. Glass optical fibers, each having a core, cladding and coating are disposed within the longitudinal aperture, the fibers extending beyond each end thereof. The coating is removed from that portion of the fibers in the midregion of the tube. The midregion of the tube is heated, collapsed about the fibers, and drawn to reduce the diameter thereof over a predetermined length. The fibers that are used in the process of making the coupler are initially provided with a coating that is too thin to provide good handleability and strength. However, the thin initial coating enables the use of a tube having a small aperture and thereby enhances the tube collapse step. After the coupler is formed, the fibers extending therefrom are overcoated. The process can be used to make other kinds of optical devices including integrated optical components.
