As the human population grows, it is critical to decrease consumption of materials from the planet and its ecosphere. The world adds 70 million people annually. The UN expects the population to grow to over 9 billion 2050. Climate change, soil degradation, unstable water supply all reduce the ability of traditional farming to satisfy food needs. Population increase and scarcity of resources and fo ...

Exploitation of new chip-scale optical frequency comb sources demands improvements in MWIR/LWIR detector performance, including: High speed (5 GHz); high sensitivity (NEP < 1pW/Hz1/2); broad spectral response (Octave); and thermo-electric cooler (TEC) operating temperature. No existing detector meets these demanding performance parameters. Phase I successfully designed and demonstrated an octave s ...

Exploitation of new chip-scale optical frequency comb sources demands improvements in the performance of MWIR/LWIR detectors. These detectors must meet the following specifications: High speed ( < 5 GHz), high-sensitivity (NEP < 1pW/Hz^1/2), broad spectral response (Octave), all at TEC operating temperatures. At present, no single detector exists that meet these demanding performance parameters. I ...

The objective of this proposal is to develop novel lead salt semiconductor quantum dot (QD) mid-infrared detectors for sensing and imaging applications. The proposed development is based on our recent study of PbSe photoconductive (PC) detector with a rec

Type II strained layer superlattice (SLS) p-n diode arrays fabricated on domestic-source GaSb substrates are a promising route to meet the critical need within DoD for large area, large format array infrared detectors. However, current SLS material quality is limiting detector performance. A quantitative, cost effective and trusted evaluation technique for measuring the SLS minority carrier lifet ...

Attacks using chemical warfare (CW) agents are a principal threat to the US homeland and deployed assets. This proposal focuses on demonstrating key capabilities required to develop a micro-gas analysis (MGA) system that provides orders of magnitude improvement in sensitivity and a very high degree of chemical selectivity to achieve false alarm rates that match laboratory gas chromatographs with ...

Optical circuits provide many benefits for large time-bandwidth signal processing in microwave photonic applications. SeTapped delay lines using surface acoustic waves (SAWs) are in use today for carrier frequencies in the MHz to 100 MHz range, and thus their general theory and efficacy are well known. In order to be widely applicable, the tapped delay line filter must be robust enough to be dep ...

Department of Defense is interested in development of small fighter-like vehicle for combined underwater and surface motions at high speeds. The vehicle requires carry weapons under water. The weapons may generate high additional drag, and drag reductionis the key aspect in design of its hybrid hull. Hydrofoil removes missiles from water at highest speeds, but the problem is to reduce the drag bef ...

"The future battlefield will feature highly advanced targeting and firepower and will therefore require significant advancements in real-time information feed back for individual soldiers. Advanced communications and sensors systems can inform the soldierand his commander of, for example, the locations and identities of hazards and details of his physical condition. To advance this goal, radio-f ...

"DoD is interested in small underwater fighter-like vehicles. These submersibles will start from submarines and must carry sensors and/or weapons at a high speed. A part of their route will be passed over the water surface in littoral environment.Drag reduction is the key issue in design of such vehicles because submerged missiles add significant hydrodynamic drag. For surface operations, hydrofoi ...
