This SBIR Phase I project proposes the feasibility study of integrated all-optical 2R regeneration and 3R optical signal regeneration devices for use as high-speed interfaces in satellite applications (solicitation AF04-043). Currently available products achieve regeneration of signals by resorting to Optical to Electrical and then Electrical to optical conversion (OEO), which results in costly, ...

Current turbomachinery designs have been optimized, for the most part, using "average flow" design concepts and tools. Future advances in engine performance, especially with regard to increasing per stage pressure ratio, stall margins, and reduced sensitivity to inlet distortion in fans/compressors, must come from innovative technologies which move beyond the current "steady flow" design space. ...

Recently, expanding wireless communication systems have presented new challenges to design and produce high quality miniature tunable phase shifters with low cost. Dymas Research proposes a novel RF phase shifter fabricated on high-performance ferreelectric films to provide tunability for adaptive microwave devices. This tunable microwave device has the advantage of achieving frequency or phase tu ...

Polarization imaging system has been explored as a method to improve target detection capabilities in remote sensing and other applications. Polarization imaging can improve target contrast, reduce clutter, aid in the defeat of intervening scatterers, and provide orientation information about various target features. The feasibility of polarization technology application in separation of a boost ...

Recent advent, and a significant progress made in the wide band gap semiconductor technology offer today a promise for a superior power amplifier. More specifically, emerging Gallium Nitrate (GaN) HEMT devices are shown to operate in extreme temperatures (~600C), exhibiting high breakdown voltages (~100V) and high current densities (~1.5A/mm). In order to meet these challenging technical requireme ...

The objectives of the proposed effort are to demonstrate the use of computational fluid dynamics (CFD) as a design tool for reducing engine development time and cost, to reduce fuel nozzle-combustor test requirements, and to demonstrate the capability of CFD to accelerate the incorporation of promising, actively controlled fuel nozzles and combustors into aircraft engines. These overall objectives ...

Electronically Steered Arrays have become important components of many military and commercial systems. The ability to steer the null of the antenna as well as the main beam is important in the presence of jamming signals, or interference from other stations. This proposal presents a MMIC based solution for the beamforming weights of a 43.5-45.5 GHz system that is highly accurate, repeatable, an ...

Directed Energy Weapon (DEW) laser or microwave-based systems are being developed for both ground and airborne applications. These applications require significant amount of power, which ranges from several hundred kilowatts to Megawatts. The laser DEW requires that the full, tightly regulated, power is available intermittently, typically 5 seconds on followed by 10 seconds off. The control of a g ...

InPhot Inc proposes to develop the enabling SiGe material and device technology for the realization of monolithic near infrared Photoreceiver at 10Gb/s data rates sensitive in the 1300 nm to 1550 nm spectral region for laser communication. We will achieve this by performing device designs to determine suitable material structures, epitaxial growth and device fabrication processes. The primary goal ...

Compact arrays of ultra-high-speed analog laser sources or lasers integrated with modulators are needed for LADAR sensors and scene generation. Multiplex, UCLA and UCSD propose a novel Monolithic Injection-Locked Analog Transmitter Array (MILATA) for wide frequency range (>2GHz) operation with greater than 60 dB optical extinction ratio. MILATA is a versatile technology platform that is built on o ...
