  • Publication number: 20040043508
    Abstract: A substrate, which that is capable of attaching biomolecules, and a method for preparing the substrate are provided. The substrate has a reactive surface that can covalently attach a polymer coating containing functional groups, which can reduce nonspecific binding of biomolecules to the surface for a biological array. Optionally, at least a portion of the substrate may be coated with an intermediate tie layer, which enhances the covalent bonding between the polymer coating with the underlying substrate. The present invention also pertains to a method that uses electrostatic blocking agents to reduce non-specific binding of proteins to a substrate, especially anhydride-modified surfaces.

  • Publication number: 20030142262
    Abstract: A non-blocking N×N cross-connect is provided that has an array of liquid crystal (LC) switches in a grid of planar optical waveguides within a light optical circuit (LOC). LC filled trenches are used in a planar optical waveguide and each trench provides the functionality of a waveguide polarization splitter, a transverse electric (TE) switch cross point, a transverse magnetic (TM) switch cross point, or a waveguide polarization combiner. By combining these elements, a cross-connect system is fabricated.

    Abstract: A non-blocking N×N cross-connect is provided that has an array of liquid crystal (LC) switches in a grid of planar optical waveguides within a light optical circuit (LOC). LC-filled trenches are used in a planar optical waveguide and each trench provides the functionality of a waveguide polarization splitter, a transverse electric (TE) switch cross-point, a transverse magnetic (TM) switch cross-point, or a waveguide polarization combiner. The planar optical waveguide has a refractive index substantially equal to the lowest index of refraction of the LC material. By combining these elements, a cross-connect system is fabricated. Also disclosed is a dynamically adjustable prism constructed with a liquid crystal material.

  • Patent number: 6415075
    Abstract: An optical signal limiter is provided for limiting transmission of a continuous wave optical signal that exceeds a preselected threshold power level. The limiter includes a body having input and output ends that is formed at least in part from a material having a negative thermal index coefficient of between about −0.5×10−4 °C.−1 and −4.0×10−4 °C.−1 and an absorption coefficient of between 1.0 to 5.0 dB/cm at wavelengths between 980-1650 nm. The limiter also includes collimating fibers mounted on the input and output ends to minimize low power signal losses across the limiter body. It may be installed at a junction between two optical fibers and is preferably formed from a curable adhesive having the aforementioned negative thermal index coefficient to obviate the need for separate bonding materials and joining steps during the installation of the limiter.
