The 3DIC concept is based on using multiple levels of thin film dielectric material, each having its own ground plane and microwave circuits, to stack up multiple circuit functions on top of each other. This approach reduces the IC footprint thereby reducing the usage of the semiconductor real estate, leading to substantial reduction in cost as well as improvement in performance. The phase 1 tec ...

This project will conceptually design and demonstrate the feasibility of a multivariate approach to the real-time measurement of cognitive workload, basedon operator psychophysiology as well as behavior, in the context of task demands. Such as approach will facilitate the development of cooperative human-computer controversy over how to implement such capabilities, including how to ascertain the ...

AstroPower proposes to develop high performance, room temperature, mass-producible, low-cost infrared detectors using liquid-phase heteroepitaxy of lattice-matched InGaAsSb and AlGaAsSb on GaSb substrates. The structure of these detectors will be a Separate Absorption and Multiplication Avalanche Photodiode (SAM-APD). This structure has proven to be an effective means of producing large gain in ...

Atlantic Aerospace offers to define, develop and analyze a new spread spectrum code acquisition technique having breakthrough potential for decreasing the product of acquisition time and acquisition processor speed for acquisition of GPS signals relative to currently employed techniques. The basis for this claim already exists in results of the company's contract an dcorporately-funded research.I ...

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 ...

Brimrose proposes to develop a relatively new class of materials to build electro-optic power limiter (EOPL) to protect optical sensors against jamming and for personnel protection against laser beams. These materials are transition metal doped II-VI semiconductors, cadmium manganese telluride (Cd1-xMnxTe) and cadmium telluride selenide (CdTe1-YSeY). Field shielding optical non-linearity in these ...

Spectrally and spatially coherent, high pulse energy, tunable mid-IR sources remain elusive. Solid-State and semiconductor lasers do not operate over the 1.5 to 5 micron wavelength range, leaving laser-pumped frequency converters, such as Optical Parametric Oscillators (OPOs), as the most viable technology. Achieving high conversion efficiency and continuous tunability in rugged OPOs has present ...

A novel, adaptive waveform coherent LADAR concept is proposed to provide a robust Automatic Target Recognition (ATR) sensor with the capability to meet Air Force objectives. The compact, rugged solid-state LADAR operates at eyesafe wavelengths and is capable of stand-off detection ranges to 20 km or more. Simultaneous precision range, Doppler and micro-Doppler target signatures are extracted wit ...
