  • Drain cover
    Patent number: 9643113
    Abstract: A drain cover includes a base portion including an outer rim and defining a collection area. The drain cover also includes a central portion coupled to the base portion and extending upward from the base portion, wherein the collection area tapers from the central portion toward the outer rim, and wherein the collection area is vertically lower adjacent the central portion relative to an outer periphery of the collection area.
    Type: Grant

  • Semiconductor lasers utilizing optimized n-side and p-side junctions
    Publication number: 20090168826
    Abstract: A semiconductor laser and a method of forming the same are provided. The n-side and p-side junctions are independently optimized to improve carrier flow. The material for the n-side cladding layer is selected to yield a small conduction to valance band gap offset ratio while the material for the p-side cladding layer is selected to yield a large conduction to valance band gap offset ratio.

  • Vertically displaced stack of multi-mode single emitter laser diodes
    Publication number: 20090103580
    Abstract: An optical source comprised of a stack of at least two laser diode subassemblies is provided. Each laser diode subassembly includes a submount and a multi-mode, single emitter laser diode. Each of the at least two laser diode subassemblies is mounted to a stepped mounting member such that the output beams from the at least two laser diode subassemblies are vertically displaced along the z-axis, horizontally displaced along the y-axis, and not horizontally displaced along the x-axis.

  • Vertically displaced stack of multi-mode single emitter laser diodes
    Publication number: 20070116077
    Abstract: An optical source comprised of a stack of at least two laser diode subassemblies is provided. Each laser diode subassembly includes a submount and a multi-mode, single emitter laser diode. Each of the at least two laser diode subassemblies is mounted to a mounting member. Means are included to vertically displace the output beams from the individual laser diode subassemblies to form an optical source output beam. In at least one embodiment, the mounting member performs the function of the vertically displacing means.
