  1. Optoelectronic Integrated Circuits Based on Single Crystal GaN Waveguides

    SBC: Apa Optics, Inc.            Topic: N/A

    We propose the exploration of single crystal GaN waveguides for the fabrication of optoelectronic integrated circuits. The feasibility of using GaN for short wavelength (up to 365 nm) OEIC's will be established in Phase I via the demonstration of a channel waveguide based phase shifter. The Al(sub x)GA(sub 1-x)N material system with its transparency from 365 nm to 12 microns, tunable refractive in ...

  2. WAVELENGTH DIVISION MULTIPLEXED OPTICAL MODULATOR FOR ADVANCED COMMUNICATION SYS

    SBC: Apa Optics, Inc.            Topic: N/A

    We propose to demonstrate the design, fabrication, and performance of an integrated optic based device which provides for both multiplexing and independent external modulation of three closely spaced wavelengths emitted by a multi-longitudinal mode laser. The innovative aspect of the proposed device is the use of an integrated optics device chip to enable coupling of the dispersed laser wavelength ...

  3. Growth of Bulk Single Crystal AlN Substrates for AlxGa1-xn Epitaxy

    SBC: Apa Optics, Inc.            Topic: N/A

    We propose a six month Phase I program to demonstrate the feasibility of growing A1N single crystals to serve as substrates for subsequent A1xGa1-xN epitaxy. Our approach is to use a low pressure, high temperature (2000 C) furnace with a temperature gradient between the A1N charge and the deposition (seed) regions. Our approach is based on several innovations. These include the use of single precu ...

  6. Commercialization of a Large-Signal Non-quasi-static Bipolar Transistor Model

    SBC: APPLIED RESOURCES CORPORATION            Topic: N/A

    Millimeter-wave circuit design requires accurate models to optimize performance, to minimize the number of preliminary designs, and to allow design centering for uniformity and high yield reducing cost and improving reliability. Existing bipolar circuit models fail at prediction of high frequency, non-linear, and switching behaviors. These models are not specified by the physical structure of the ...

  7. Nitrogen Source for Molecular Beam Epitaxy by Photofragmentation of Ammonia

    SBC: Applied Semiconductor            Topic: N/A

    Epitaxial growth of the aluminum gallium nitride (AlGaN) material system by molecular beam epitaxy (MBE) has been hindered by the lack of a suitable nitrogen source. The deposition of AlGaN at typical MBE growth temperatures results in nitrogen deficient films that suffer from low growth rates and high n-type background carrier concentrations. This problem has recently been addressed in MBE by inc ...

  9. Low-Cost Chemically Bonded Ceramic Prototype Tooling for Fabrication of Composites

    SBC: Cercon, Inc.            Topic: N/A

    The proposed investigation will characterize the physical properties of Chemically Bonded Ceramic (CBC) tooling currently being evaluated as production tooling by the automotive and furniture industries for fabricating plastics and molded organic foams. This information will be used to modify the tooling mix compositions to optimize the properties required to successfully form graphite reinforced ...

  10. 4H-Silicon Carbide for High Temperature Power MOSFETs

    SBC: CREE RESEARCH, INC.            Topic: N/A

    THE RAPID DEVELOPMENT OF THE TECHNOLOGY FOR PRODUCING HIGH QUALITY SINGLE CRYSTAL SiC WAFERS AND THIN FILMS PRESENTS THE OPPORTUNITY TO FABRICATE SOLID-STATE DEVICES WITH POWER-TEMPERATURE CAPABILITY FAR GREATER THAN DEVICES CURRENTLY AVAILABLE. THIS CAPABILITY IS IDEALLY SUITED TO THE APPLICATION OF POWER CONDITIONING ON THE ALL-ELECTRIC AIRPLANE, TURBINE ENGINE ACTUATORS, AND SPACE-BASED POWER S ...
