ABSTRACT: In this project, Soluxra, LLC will team up with Prof. Alex Jen at the University of Washington to streamline the scale-up synthesis for highly efficient organic electro-optic (EO) material systems, and optimize their processing conditions to ensure device end-users will get high EO activity (Pockels coefficient>200 pm/V). The design of these materials will leverage the recent remarkable ...

ABSTRACT: State of the art Orbital Transfer Vehicle systems require the demanding combined requirements of both high Thrust-to-Power (greater than 120 mN/kW) and high specific impulse (greater than 3000 s), all at constant power. The 25 kW PROTEAN system is a two-stage plasmoid thruster which adds an secondary auxiliary Neutral Entrainment (NE) stage to the ElectroMagnetic Plasmoid Thruster (EMPT ...

ABSTRACT: Study of non-stationary phenomena in turbulent combusting flows requires spatial measurements of a set of parameters at kHz rates. Ideally these parameters would include the velocity , temperature, and a relevant species concentration. In response to this need, ORBITEC and the University of Wisconsin-Madison propose to develop a technique to measure velocity, temperature, and OH conce ...

ABSTRACT: An instrument measuring volume charges in thin dielectric films is proposed. The instrument utilizes an enhanced Pulsed Electro-Acoustic (PEA) technique and delivers submicron spatial and at least 0.1 micro-Coulombs per cubic centimeter resolutions of the charge density. Traditional PEA instruments suffer from significant signal loss due to acoustic mismatches between the testing materi ...

ABSTRACT: This Phase II proposal seeks to develop a prototype speech segregation system that can significantly improve intelligibility of noisy speech for human listeners, a technical challenge that has eluded a solution for decades. Motivated by principles of auditory perception, system development is based on an auditory scene analysis approach to speech segregation. This approach differs subst ...

ABSTRACT: In phase I of this program, we proposed to develop and validate detailed designs for highly scaled silicon photonic-electronic chips for applications relevant to the DOD in high-bandwidth data communication. This effort has been closely coordinated with the OPSIS (Optoelectronic Systems Integration in Silicon) project being led at the University of Washington, an effort to create an ope ...

ABSTRACT: Carbon dioxide feed stock can be converted into fuels of solid, liquid or gas phase by chemical, electrolytic, photocatalytic and photo-electrocatalytic methods. Reduction of CO2 to fuel form of any phase requires energy. The reduction process should be energy efficient so that we do not spend more energy and emit more (indirect) CO2 in the process of converting CO2. From this point of ...

ABSTRACT: Quantum-dot gain medium in semiconductor lasers exhibit higher resistance to radiation induced damage. Irradiated diode lasers comprising quantum-dot gain medium demonstrated lasing two orders of magnitude beyond the maximum dose sustainable by quantum-well semiconductor lasers. These studies point to the strong potential for achieving a radiation resistant diode laser. Additionally, ...

ABSTRACT: The goal of the Space Test Program operated by the US Air Force is to enable the rapid development of emerging space technologies by providing economical flight opportunities to increase a technology"s TRL. In particular, the CubeSat form factor has emerged as an economical platform for testing technolo-gies that can be made to fit in the 10x10-30 cm form factor. Unfortunately, the lack ...

ABSTRACT: A subminiature laser sensor system operating at 1550 nm for use on micro-class unmanned air vehicles (UAV) is proposed. The system can be electronically reconfigured to function as a: laser designator, laser spot tracker, laser range finder and a proximity sensor. This modular system occupies less than 4 cubic inches and has a range of 0.5 km2.5 km in a slightly larger version. A pas ...
