摘要： The invention relates to a method for manufacturing a hihg-tensile strength optical waveguide with a plastic layer of the epoxy-acrylate type located on the lightguide fiber, wherein a radiation-hardenable prepolymer is applied to the lightguide fiber immediately after the fiber-drawing process. The invention provides for the use in such a method of a preopolymer, which can be hardened by actinic radiation, of at least one acylated hydroxy ester of acrylic and/or methacrylic acid and an epoxide with n.ltoreq.3 epoxide groups per molecule. The optical waveguides manufactured by the method according the present invention are suitable particularly for purposes of optical information transmission.

摘要： The present invention is directed to an improvement in a magneto-optical device having a light waveguide for conducting light characterized by the light waveguide being a cladded optical fiber having a core of quartz glass and a cladding of synthetic material. This improvement provides an improved method of using the magneto-optical device by suppressing distortions of polarized light by reducing birefringence in the waveguide by using a waveguide comprising an optical fiber having a quartz glass core and a cladding of synthetic material.

摘要： A method and apparatus for producing a light conducting fiber having a core disposed in a loose fitting cladding tube characterized by a double crucible arrangement having a first crucible for a melt of the material for the cladding tube and a second crucible for the melt of the material of the core. The second crucible has an orifice of a given diameter and the first crucible has a ring-shaped orifice with an inner diameter greater than the given diameter of the orifice of the second crucible with the center of the ring-shaped orifice being arranged substantially on a central axis of the orifice of the second crucible so that a core drawn from the orifice of the second crucible is substantially concentrically disposed within the tube of material drawn from the ring-shaped orifice. In each embodiment of the apparatus, the first crucible is an annular crucible having a ring-shaped cross section and the second crucible is either disposed above the first crucible so that the core drawn from the second crucible passes through a hollow passage or is disposed in the central space either with spacing from the walls of the first crucible or with the inner wall of the first crucible forming the wall of the second crucible. Preferably, an inert gas is injected between the core and the tube to prevent collapsing of the tube during the drawing of the fiber.

摘要： A process for the production of gradient fibers of glass by depositing layers of glasses having selected indices of refraction and then drawing fibers therefrom. The process is carried out by sequentially introducing a plurality of glass masses to form layers having progressively higher refractive index of refractions. The resulting layers are formed into an unitary body which is drawn into an optic fiber.
