    Abstract: A spectrometer system includes an optical assembly for collimating light, a micro-ring grating assembly having a plurality of coaxially-aligned ring gratings, an aperture device defining an aperture circumscribing a target focal point, and a photon detector. An electro-optical layer of the grating assembly may be electrically connected to an energy supply to change the refractive index of the electro-optical layer. Alternately, the gratings may be electrically connected to the energy supply and energized, e.g., with alternating voltages, to change the refractive index. A data recorder may record the predetermined spectral characteristic. A method of detecting a spectral characteristic of a predetermined wavelength of source light includes generating collimated light using an optical assembly, directing the collimated light onto the micro-ring grating assembly, and selectively energizing the micro-ring grating assembly to diffract the predetermined wavelength onto the target focal point, and detecting the spectral characteristic using a photon detector.

    Abstract: “Super-hetero-epitaxial” combinations comprise epitaxial growth of one material on a different material with different crystal structure. Compatible crystal structures may be identified using a “Tri-Unity” system. New bandgap engineering diagrams are provided for each class of combination, based on determination of hybrid lattice constants for the constituent materials in accordance with lattice-matching equations. Using known bandgap figures for previously tested materials, new materials with lattice constants that match desired substrates and have the desired bandgap properties may be formulated by reference to the diagrams and lattice matching equations. In one embodiment, this analysis makes it possible to formulate new super-hetero-epitaxial semiconductor systems, such as systems based on group IV alloys on c-plane LaF3; group IV alloys on c-plane langasite; Group III-V alloys on c-plane langasite; and group II-VI alloys on c-plane sapphire.

    Abstract: A device for mounting a data transmission apparatus to a rotating, tapered and instrumented shaft is provided. This device permits attachment without interfering with shaft rotation or the accuracy of data output, and prevents both radial and axial slippage of the data transmission apparatus. The mounting device consists of a sleeve assembly which is attached to the shaft with clamps that are situated at some distance removed from the instrumented area of the shaft. The data transmission device is secured to the sleeve such that the entire assembly rotates with the shaft. Shim adjustments between sleeve sections assure that a minimum compressive load is transferred to the instrumented area of the shaft and a rubber lining is affixed to a large portion of the interior surface of the sleeve to absorb vibration.

    Abstract: A bearing assembly retainer ring has pockets for holding cylindrical rollers in arcuately spaced relationship about a central axis of the retainer ring. Each pocket has two end faces that are spaced axially of the retainer ring and two side faces that are spaced laterally of the axial spacing between the two end faces. The pocket extends radially through inner and outer peripheral edges of the retainer ring to receive a roller therein having a diameter which is greater than the radial span of the pocket end faces so that the roller extends beyond the inner and outer peripheral edges of the retainer ring. The axial spacing between the pocket end faces is slightly greater than the axial length of the roller to provide restricted clearances between the ends of the roller and the end faces of the pocket when the roller is centered within the pocket. Chamfers are provided on the end faces of the pockets at the inner and outer peripheral edges thereof. These chamfers enable the roller to pivot within the pocket from a position wherein the roller is aligned axially between the pocket end faces to a cocked position wherein both end faces of the pocket contact the roller and/or the side faces of the pocket contact the roller to resist further pivotal movement.

    Abstract: A spectrometer system includes an array of micro-zone plates (MZP) each having coaxially-aligned ring gratings, a sample plate for supporting and illuminating a sample, and an array of photon detectors for measuring a spectral characteristic of the predetermined wavelength. The sample plate emits an evanescent wave in response to incident light, which excites molecules of the sample to thereby cause an emission of secondary photons. A method of detecting the intensity of a selected wavelength of incident light includes directing the incident light onto an array of MZP, diffracting a selected wavelength of the incident light onto a target focal point using the array of MZP, and detecting the intensity of the selected portion using an array of photon detectors. An electro-optic layer positioned adjacent to the array of MZP may be excited via an applied voltage to select the wavelength of the incident light.

    Abstract: Disclosed are embodiments of a semiconductor structure, a design structure for the semiconductor structure and a method of forming the semiconductor structure. The embodiments reduce harmonics and improve isolation between the active semiconductor layer and the substrate of a semiconductor-on-insulator (SOI) wafer. Specifically, the embodiments incorporate a trench isolation region extending to a fully or partially amorphized region of the wafer substrate. The trench isolation region is positioned outside lateral boundaries of at least one integrated circuit device located at or above the active semiconductor layer of the SOI wafer and, thereby improves isolation. The fully or partially amorphized region of the substrate reduces substrate mobility, which reduces the charge layer at the substrate/BOX interface and, thereby reduces harmonics. Optionally, the embodiments can incorporate an air gap between the wafer substrate and integrated circuit device(s) in order to further improve isolation.
