The Goal of this STTR is to develop a high speed, high power, waveguide based modulator (phase and amplitude) and investigate its use as a pulse slicer. The key innovation in this effort is the use of potassium titanyl phosphate (KTP) waveguides making the high power, polarization based waveguide amplitude modulator possible. Furthermore because it is fabricated in KTP, the waveguide component w ...

This NASA Phase II STTR effort will develop domain-engineered magnesium oxide doped lithium niobate (MgO:LN) for LIDAR-based remote sensing and communication applications. Use of bulk and waveguide-based domain engineered MgO:LN will allow the manufacture of highly efficient and compact, wavelength conversion modules for second-harmonic generation (SHG), sum-frequency generation (SFG), and parame ...

Bridger Photonics and the University of Arizona will develop a passive multi-band compressive sensor for imaging and object recognition applications. The Army has identified a need for multi-band imagery for intelligence, surveillance and reconnaissance missions among others. Multi-band systems offer enhanced discrimination capability and the ability to perform in adverse conditions (at night, smo ...

Army quantum information researchers have an immediate need for improved stable, narrowband violet and UV laser sources with 10100 mW output and 10 MHz10 GHz tuning. These sources are required for numerous ion and atom qubits functions including photoionization, Doppler cooling, state initialization, and detection. The cost and complexity of currently available UV lasers hampers current efforts ...

This work will continue the use of numerical methods to determine optimal design parameters for a compact hybrid fuel cell power system driven by a statistically determined load profile. Detailed physics-based models will be used to represent the bahavior of the components in the hybrid system. The components considered in the hybrid system for Phase II will be a PEM fuel cell, Li-ion batteries an ...

Sensor Electronic Technology, Inc. proposes to use QD-like fluctuations of InGaN QW with controllable spatial distribution for high efficiency green LEDs. We will investigate both theoretically and experimentally the performance of green InGaN MQW structures with fluctuations of composition and thickness of InGaN quantum wells. Both types of these fluctuations would lead to the spatial localizatio ...

The goal of this effort is to develop a compact, rugged, electrically efficient, tunable semiconductor laser for the purpose of injection seeding Nd:YAG lasers in NASA lidar systems for remote sensing and atmospheric profiling. A highly stable low power seed laser plays a crucial role in these systems by keeping the high power, Q-switched, Nd:YAG laser at a fixed wavelength and single mode. In add ...

Many Unites States Army, and other Department of Defense (DoD) sites, are contaminated with a variety of contaminants including highly energetic compounds, such as 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), chlorinated aliphatics (such as trichloroethylene,TCE) and chlorinated aromatics. These compounds often persist in soil or groundwater for extended periods of t ...

Programs such as Airborne Laser and Space-Based Laser require highly mass efficient structures. Because of their high specific strength and stiffness this naturally leads to graphite fiber reinforced polymer (GFRP) materials for many system components. In fluid storage tank applications GFRP laminates often develop microcracking when subject to cryogenic temperatures and/or stresses due to press ...
