ABJ Integration Technologies, Inc. proposes to model a vertically optically interconnected stack of silicon integrated circuits to form a three dimensional system. This 3D system will utilize through-substrate optoelectronic communication to which the package and silicon are optically transparent. System optimization for user specifications will include materials and components such as emitters ...

The purpose of the proposed R&D is to develop and demonstrate an innovative lagacy engineering methodology which supports the development and maintenance of complex, heterogeneous systems employing COTS and legacy components.

This Small Business Innovation Research Project will determine the advantages and disad-vantages of fibrous/polymeric composite materials over traditional material (steel) for retrofitting key civilian facilities against terrorist bomb attack. Retrofit techniques we will evaluate are: strengthening fully and partially exposed columns with composite wraps or shells, masonry walls with bonded comp ...

To develop faster and larger pulse-coupled neural networks (PCNN) for image processing, Bosonics will design and simulate a 64 by 64 neuron chip with optical inputs and outputs. PCNN have been shown to be effective at fast analog pre-processing of detector data, image transforms, and automatic target recognition. In Phase I Bosonics will 1) define the image processing application specifications ...

This project develops low-cost optical beamscanners using fast binary amplitude modulators. The modulators are solder-bumped to silicon drive circuits which have a programmable architecture for rapid, flexible array addressing. The multiple quantum well (MQW) based modulators operate at 850-860 nm with a random access speed over 100 MHz---faster than any known scanner. Preliminary simulation an ...

Modern sensors and communication equipment in both the military and commercial sectors require low-cost, small size antennas and circuitry. We propose to investigate low-cost medium-to high-volume manufacturing methods for compact arrays of conformal waveguide. The goals in Phase I will be to investigate and determine the best antenna technology and fabrication methods for military fuse and seeker ...

This proposal describes a new optical phase-shifter technology incorporating analog ferroelectric liquid crystal (FLC) materials. This technology will be used to produce a phased-array beamsteerer that can be reconfigured in under 100 microseconds. Due to the analog behavior, the device promises high diffraction efficiency and low sidelobe amplitude. Because FLC materials are used, rapid switchi ...

We propose to develop a high frame-rate, large-area, amplitude-only SLM for use in atmospheric correction. The Phase I will demonstrate the concept through the fabrication/evaluation of amplitude-only modulators, as well as an addressing structure that is economical for large-areas. Phase II will scale the addressing structure to 128X128 or higher density, for fabrication of large area amplitude ...

Chrome replacement and corrosion protection coatings in thermal environments is needed. Combustion chemical vapor deposition (CCVDsm), a process invented by the principal investigator, is the only open atmosphere CVD technique for ceramics and metals. The CCVD method has been shown to inexpensively and quickly apply dense, adherent thin films in a continuous manner. This technology can be use ...

Currently, thermal spray (flame and plasma spray) is the only single step method of applying most metal and non-oxide ceramic coatings to large objects. These coatings are usually of a low quality, and thin films cannot be applied. An in situ deposition technique that inexpensively and easily applies nitrides, carbides and other non-oxide thin or thick films in an environmentally friendly manner i ...
