    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.

    摘要： This invention relates to a method of drawing twist-free optical fibers; it is particularly useful for drawing polarization retaining single-mode optical fibers having azimuthal inhomogeneities. There is applied to the fiber, during the drawing thereof, a coating having a non-circular cross-section, the azimuthal inhomogeneity of the fiber being positioned in a substantially constant orientation with respect to the non-circular cross-section of the coating. In another embodiment, a plurality of fibers having azimuthal inhomogeneities are drawn from a plurality of preforms that are properly oriented in the draw furnace. The fibers are drawn through the same coater so that the azimuthal inhomogeneity of each fiber is oriented in a substantially constant relationship with respect to the azimuthal inhomogeneities of the remaining fibers in the coating.

    摘要： A plurality of optical waveguide preforms are simultaneously formed by depositing on a plurality of starting members layers of glass soot to build up a coating on each starting member. The soot layers are deposited by traversing a series of burners along the starting members in such a manner that a given one of the burners traverses the first starting member from a first end thereof to a second end thereof to form a layer of soot thereon. The remaining burners of the series similarly traverses the first starting member, a plurality of burners traversing the first starting member at any given time. After the first burner has traversed the first starting member it similarly traverses the second starting member. After the last of the series of burners has begun its traverse along the first starting member, the first of the series of burners completes its traverse of the second starting member and again begins traversing the first starting member immediately following the last of the series of burners.

    摘要： A single-mode optical waveguide is constructed in a manner such that the core thereof is subjected to a stress-induced birefringence. A coating of core glass soot is deposited on the surface of a cylindrical mandrel, and a coating of inner cladding glass soot is deposited on the core glass soot. The mandrel is removed and the resultant porous preform is consolidated to form a hollow dense glass preform. The preform aperture is closed at both ends. Diametrically opposed slabs are removed from the inner cladding region of the consolidated preform. The resultant article is evacuated, heated and stretched to close the aperture and form a preform foreproduct having two opposed rounded sides and two opposed flattened sides. The foreproduct is coated with a layer of outer cladding glass soot having a thermal coefficient of expansion which differs from that of the inner cladding glass by at least 1.times.10.sup.-7 /.degree.C. The resultant composite structure is consolidated to form a draw blank which can be drawn into an optical fiber.

    摘要： A device for treating fluids, such as automotive exhaust gases is provided, as well as a method of manufacturing such a device. The device provides a honeycomb structure, a matrix of ceramic walls that defines a plurality of parallel, fluid-conducting cells oriented along an axis, arranged in a stacked or discontinuous configuration between an inlet and outlet, where adjacent layers of honeycomb structure are separated by layers of air spaces. Each matrix layer has opposing faces that defines the inlets and outlets of the cells, and a peripheral portion or peripheral region including an outer skin. The peripheral portions or peripheral regions of adjacent stacked ceramic layers are mutually contiguous to prevent fluid flowing through the stacked ceramic layers from leaking between said outer skins.

    摘要： An optical fiber having optical characteristics that systematically vary along its length is made by inserting a plurality of cylindrical tablets into a cladding glass tube and overcladding the tube with particles of cladding glass. Each tablet contains a core region, and it optionally contains a layer of cladding glass Adjacent tablets are capable of forming optical fiber sections having different optical properties. Prior to consolidating the glass particles, chlorine flows through the tube and over the tablets. When the tube begins to sinter, the chlorine flow is stopped and the sintering particles generate an inwardly directed force that causes the tube to collapse inwardly onto the tablets which concurrently become fused to each other. The resultant draw blank can be drawn into a low loss optical fiber. This method is particularly useful for making dispersion managed single-mode optical fibers.
