摘要： Disclosed is a dispersion compensating and dispersion slope compensating single mode optical waveguide fiber. The refractive index profiles of waveguide fibers in accord with the invention are disclosed and described. These index profiles provide a waveguide fiber having negative total dispersion and negative total dispersion slope so that a standard waveguide fiber is compensated over an extended wavelength range. A telecommunications link using the fiber in accord with the invention is also disclosed and described. A standard fiber to compensating fiber length ratio in the range of 1:1 to 3:1 is shown to give optimum link performance with respect to limiting non-linear dispersion effects.

摘要： Disclosed is a dispersion controlled optical waveguide fiber, and telecommunication systems using such a waveguide fiber, in which the end to end total dispersion and total dispersion slope is controlled by varying the refractive index profile along the fiber length. The waveguide fiber includes length portions each of which is characterized by total dispersion having a magnitude and sign and total dispersion slope having a magnitude and sign. The magnitudes and signs of total dispersion and total dispersion slope of respective length portions are chosen to provide for the optical waveguide fiber a desired end to end total dispersion and total dispersion slope. An advantage is achieved in the present invention by designing the refractive index profiles of the length portions to have total dispersion and total dispersion slope of opposite sign.

摘要： A method of making an optical fiber having an oblong core comprising the steps of depositing layers of core glass particles and cladding glass particles on an enlarged mandrel, removing the mandrel to form a tubular porous preform, consolidating the porous preform to form a dense glass preform, evacuating the central hole of the dense glass preform while stretching that preform to collapse the central hole thereof and form a flattened rod, applying cladding material to the rod, and drawing the resultant composite to form an optical fiber. To facilitate the flat collapse of the central hole of the dense glass preform and to cause the core to have a large aspect ratio, the inside diameter-to-outside diameter ratio of the dense glass preform should be within the range of 0.3 to 0.9. For preferred core and cladding glasses, this ratio should be between 0.5 and 0.6. Also, the mandrel diameter should be at least 12 mm, and it is preferably between 25 mm and 50 mm.

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.
