Patents by Inventor Kenneth Gerard Glogovsky

Kenneth Gerard Glogovsky has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6895134
    Abstract: The invention is an optoelectronic device and method of fabrication where at least two optical devices are formed on a single semiconductor substrate, with each optical device including an active region such as a multi-quantum well region. The active devices are spatially separated and optically coupled by a passive waveguide formed over the substrate which provides butt joints with the active regions. The butt joints can be optimized independently from the active regions thus improving yield.
    Type: Grant

    Date of Patent: May 17, 2005
    Assignee: Triquint Technology Holding Co.

  • Patent number: 6607933
    Abstract: A beam expander for providing coupling between a semiconductor optical device and an optical fiber comprises a double layer structure that may be integrated with the optical device. The first, underlying layer of the expander comprises a relatively high refractive index material (e.g., 3.34), thus providing improved coupling efficiency between the optical device and the fiber. The second, covering layer of the expander comprises a relatively low refractive index material (e.g., 3.28), for providing the large mode size desired at the fiber input. The parameters of each layer can be adjusted independently, allowing for the two criteria (coupling efficiency and mode size) to be separately optimized.

  • Patent number: 6107110
    Abstract: A method and apparatus for achieving alignment between a spray etcher nozzle and a semiconductor (either microelectronic or optoelectronic, for example) wafer surface. A spray nozzle tip is temporarily removed from the spray nozzle and an illumination source, such as a low power laser, is activated and inserted in its place. The laser emission illuminates the wafer surface and, by adjusting the position of the nozzle, alignment between the nozzle and wafer can be achieved. Once aligned, the nozzle is locked in place and the laser is replaced with the conventional spray nozzle tip.

  • Patent number: 6030903
    Abstract: A method for non-destructively determining the amount of undercutting in a hidden layer of material disposed on a substrate after device patterning by etching. The method involves forming at least two lines of etch resistant material of increasing width over the hidden layer of material of the substrate and inspecting the lines after etching for a given time period to determine how many lines have been removed. The width dimension of the largest removed line corresponds approximately to the amount of undercut for two sides in the hidden layer of material after etching for the given time period.
