    Abstract: A tapered optical waveguide includes a tapered waveguide section formed of a polymer. The tapered waveguide section has an optical fiber coupling end and a waveguide coupling end opposite the optical fiber coupling end with each of the optical fiber coupling end and the waveguide coupling end being generally planar. The optical fiber coupling end has a larger area than the waveguide coupling end to define a horizontal and vertical taper between the optical fiber coupling end and the waveguide coupling end. An optical system incorporating the tapered polymer waveguide is also disclosed.

  • Publication number: 20050166446
    Abstract: An apparatus for the delivery of toxicant to vermin includes an expandable conduit having an entry and exit for vermin, and which is expandable upon installation into an area determined to be suitable for vermin control. A toxicant is placeable in the expanded conduit such that vermin will contact the toxicant when passing through the conduit. In another apparatus, a toxicant is disposed within a conduit having an entry and exit for vermin. The toxicant is secured within the conduit to prevent spillage of the toxicant upon installation of the apparatus. The toxicant may be preloaded in a container. Methods for using the apparatuses are also described.
