Award Data

Correlations and convolutions are fundamental tools of signal and image processing. Applications include object recognition, automatic tracking and guidance, machine vision for automated manufacturing processes, autonomous vehicles, and general purpose image processing such as searching and analyzing graphical data bases. Optical systems can perform these operations enormously faster than electron ...

Optical interconnects are required for high speed opto-electronic packaged computing systems for fast image processing for missile interception and fast target identification. However, existing free space optimal interconnection suffers from diffraction limitation of interconnect line density and requires many large and sophisticated beam collimation, focusing, interconnect reconfiguration element ...

PPT, in collaboration with the Jet Propulsion Laboratory, proposes to develop a manufacturable packaging technology for monolithic Wavelength Division Multiplexing (WDM) laser arrays for all-optical fiber communications. The packaging technology will include coupling from a monolithic laser array to individual fibers and a microwave feed for each of the individual elements, all in a hermetically s ...

The feasibility of chemical beam epitaxy to grow ultrahigh quality GaN thin films will be developed. This process will allow the growth of GaN on high thermal conductivity substrates and enable the fabrication of precision superlattice structures. GaN will be grown using Ga effusion cells and ammonia-in an ultrahigh vacuum environment. This growth rate will be in the 1 micron per hour range at tem ...

In this Phase I STTR, Sterling Semiconductor--in cooperation with the University of Colorado at Boulder--will develop novel heterojunction bipolar transistor (HBT) semiconductor devices for microwave applications. Specifically, the team will develop I gallium nitride (GaN)/silicon carbide (SIC) N-p-n HBTs, consisting of a gallium nitride emitter on a p-type silicon carbide base and an e-type silic ...

The Theseus Logic/SUNY-Stony Brook team is proposing to develop, demonstrate and commercialize Rapid Single Flux Quantum (RSFQ) circuit designed using NULL Convention Logic (NCL). Phase I of this program will demonstrate, by simulation and modeling, the feasibility of implementing logic gate structures in RSFQ technology which can exploi the effective delay insensitivity of NCL. In Phase II the te ...

This Phase I STTR effort will be focused on fabricating and scientifically characterizing Mo/Re (59 Mo-41 Re), and W-25Re alloys with other alloying additions such as small % of dispersion strengthening materials such as zirconia, hafnia, tungsten carbide, Hafnium (Hf), Zirconium, TaC, Hf-based carbides in select geometrical shapes using UTRON Kinetics''s innovative, and cost-effective Combustion ...

The Missile Defense Agency (MDA) seeks technical investigations related to the development and application of advanced electronic materials, processes, and devices to meet its need for radiation hardened, high performance electronics for critical space and missile applications. With the advent of smaller transistor dimensions and reductions in price per bit, significant changes in materials and pr ...

Gallium Nitride (GaN) substrates are ideal materials for fabrication of high-power and high-frequency devices based on III-V materials. The current state-of-the-art Chemical Mechanical Polishing (CMP) methods are plagued by several challenges, including, surface charge affects due to surface contamination, and sub-surface damages, which can limit the quality of III-V devices. Furthermore, there is ...

This Phase I STTR program seeks a new fabrication method to produce stronger (>100 kpsi) and tougher (>10 MPa m1/2) ultra high temperature Ta-Hf-C-based composites (UHTC) with an outstanding oxidation resistance for use as thermal protection systems for hypersonic applications, as well as for advanced rocket nozzle throat components. UES will apply a novel "Top Down" approach to control the micro ...
