Patent number: 7362938Abstract: Holey optical fibers (e.g. photonic fibers, random-hole fibers) are fabricated with quantum dots disposed in the holes. The quantum dots can provide light amplification and sensing functions, for example. When used for sensing, the dots will experience altered optical properties (e.g. altered fluorescence or absorption wavelength) in response to certain chemicals, biological elements, radiation, high energy particles, electrical or magnetic fields, or thermal/mechanical deformations. Since the dots are disposed in the holes, the dots interact with the evanescent field of core-confined light. Quantum dots can be damaged by high heat, and so typically cannot be embedded within conventional silica optical fibers. In the present invention, dots can be carried into the holes by a solvent at room temperature. The present invention also includes solid glass fibers made of low melting point materials (e.g. phosphate glass, lead oxide glass) with embedded quantum dots.Type: GrantFiled: August 31, 2006Date of Patent: April 22, 2008Assignees: Virginia Tech Intellectual Properties, Inc., Lambda Instruments, Inc.Inventors: Erik Herz, Carvel Holton, Kenith Meissner, Corey Paye

Publication number: 20020111673Abstract: The invention provides tailored, biocompatible conduits for use as, for example, stents, vascular grafts, and drug delivery devices, and methods of making the conduits. The conduits are formed from a resin-impregnated matrix that is introduced to a site of interest in a malleable state, formed into a desired shape, and cured by exposure to radiant energy. The radiant energy may be visible light.Type: ApplicationFiled: December 14, 2001Publication date: August 15, 2002Inventors: Carvel Holton, Brian Love, Andre A. Muelenaer, Patricia Dolez
