Patent number: 7978946Abstract: An optical fiber includes a glass fiber having a glass core and a cladding which contains voids spaced apart from the core. The voids act as trapping sites for ingressing molecules from the surrounding environment, thereby reducing the effect of such molecules on the fiber's light-transmission properties.Type: GrantFiled: July 16, 2004Date of Patent: July 12, 2011Assignee: Verrillon, Inc.Inventors: Imtiaz Majid, Abdel Soufiane, Kanxian Wei, Gary Drenzek, Chih-Hao Wang

Patent number: 7003984Abstract: A hybrid method of and apparatus for producing a structure capable of being drawn into an optical fiber. The method includes the steps of conducting vapor-phase reactants into an interior region of a glass tube, conducting aerosol form reactants into the interior of the glass tube. The tube is exposed to a heat, thereby causing a reaction among the vapor-phase and aerosol reactants. The reaction yields a product, in a solid form, within the tube. The apparatus includes a reaction tube, a vapor-phase reactant conduit, an aerosol-form conduit, and a heat source. The vapor-phase and aerosol-form reactant conduits facilitate introduction of vapor-phase and aerosol-form reactants into the reaction tube. The aerosol-form reactants are introduced proximate to a reaction zone created by the heat source. The aerosol-form reactants conduit and heat source travel the axial length of the reaction tube.Type: GrantFiled: April 30, 2002Date of Patent: February 28, 2006Assignee: Verrillon, Inc.Inventor: Abdelouahed Soufiane

Patent number: 6636675Abstract: The invention is directed toward an optical fiber that reduces the cladding mode coupling loss (CMCL) therein. The fiber includes a core, a cladding concentrically surrounding the core, and at least one lossy region concentrically surrounding the core. The lossy region is disposed within the cladding and is slightly displaced radially from the core.Type: GrantFiled: August 3, 2001Date of Patent: October 21, 2003Assignee: Verrillon, Inc.Inventor: Abdelouahed Soufiane

Patent number: 6608956Abstract: A polarization-preserving optical fiber with a high pump-radiation absorption efficiency including a core, a primary cladding surrounding the core, stress members disposed within the primary cladding, and a secondary cladding surrounding the core, primary cladding and stress members. The stress members and the primary cladding have different thermal responses, thereby inducing birefringence within the fiber. The cladding and stress members cooperate to direct light, propagating through the fiber, into the core.Type: GrantFiled: August 3, 2001Date of Patent: August 19, 2003Assignee: Verrillon Inc.Inventor: Abdelouahed Soufiane
