  • EDGE-EMITTING LASER CHIP WAFER LAYOUT THAT FACILITATES ON-WAFER TESTING OF THE LASERS
    Publication number: 20160211644
    Abstract: Edge-emitting laser chip wafer layouts are provided that enable a variety of tests to be performed while the chips are on the wafer, including side-mode suppression ratio (SMSR) tests. The laser chip wafer layouts include turning mirrors that direct light passing out of at least one of the facets of the chips away from the wafer. Directing the light out of the wafer in this manner allows external test and measurement equipment to perform SMSR testing on the chips prior to singulation.

  • Antimicrobial polymer latexes derived from unsaturated quaternary ammonium compounds and antimicrobial coatings, sealants, adhesives and elastomers produced from such latexes
    Patent number: 6900265
    Abstract: An improved method of making CASE materials is provided, wherein the method utilizes a polymer latex derived from at least one ethylenically unsaturated monomer and at least one polymerizable surface active agent. The polymerizable surface active agent is capable of co-polymerization with traditional monomers and is preferably substantially completely consumed during the course of the polymerization. Latex polymers produced by the method of the present invention are well suited for use in coatings, adhesives, sealants, elastomers. Additionally, the present invention relates to improved coating, adhesive, sealant and elastomer (CASE) materials utilizing polymer latexes derived from various monomers and ethylenically unsaturated amine salts of sulfonic, phosphoric and/or carboxylic acids.

  • Stepwise formation of multilayered nanostructures from macromolecular precursors
    Patent number: 6022590
    Abstract: A two-step adsorption process for producing ordered organic/inorganic multilayer structures is provided. Multilayered films are formed on metallic and nonmetallic substrates by alternate adsorption of a cationic polyelectrolyte and anionic sheets of a silicate clay. The two-step adsorption process is not only fast but allows also for preparation of multilayer elements of thicknesses greater than about 2200 Angstroms on silicon, and greater than about 1500 Angstroms on gold, silver, and copper.
