ABSTRACT: This Phase I effort will involve the development of an ultra low cost, high specific power, modular and flexible solar array module using currently available thin-film solar cells, innovative interconnects, and flexible encapsulation. The high efficiency thin-film solar cells will enable high specific power and flexibility in the module. The interconnect scheme and encapsulation will a ...

ABSTRACT: This Phase II STTR research proposal aims to demonstrate an antenna coupled phase modulator based on an Electro-optic (EO) polymer refilled slot photonic crystal waveguide (PCW) for operation in the Q band. The goal is to detect field strengths of 100uW/m^2 in an Intensity Modulation Direct Detection (IMDD) scheme using subwavelength antennas. The EO polymer is the SEO125 provided by Dr ...

We propose a rapid mapping and 3-D visualization system especially suited for inside buildings, tunnels, urban canyons, and other environments where GPS may be poor or not available. The system--which was fully demonstrated in our Phase I effort-- includes mobile Sensor Nodes that wirelessly supply compressed 3D range data and color imagery to a central Fusion Node. The Fusion Node runs 3D recon ...

Vibrationally resonant sum-frequency generation (SFG) spectroscopy is a second order nonlinear optical technique that features high chemical selectivity and a set of selection rules that makes it an ideal complement to coherent Raman scattering (CRS) as an imaging tool. Attempts have been made to construct high-resolution, high speed SFG microscopes, but to date both the resolving power and image ...

The problem/situation that is being addressed is the development and improvement of compact laser- driven x-ray sources for ultrafast characterization of interest to the DoE. While much progress has been made in the development of table-top x-ray sources, with high harmonic sources and atomic soft x-ray lasers presently allowing for a large number of experiments to be conducted in small laborator ...

There is an ongoing effort to replace high activity radioactive sources that could pose a risk for use as terrorist weapons with non-radioisotope based technologies. Currently radioactive sources serve a number of critical needs including the treatment and diagnosis of disease, inspection and certification of critical mechanical structures, the sterilization of food and medical products, ...

Access to clean water is a global problem that has led to the development of multiple desalination techniques. All techniques strive to reduce the cost of desalinating water to provide clean water in a cost effective manner. Capacitive deionization (CDI) is a new technique that can reduce the cost of ownership by ~85% compared with reverse osmosis for brackish water. This project will further im ...

ABSTRACT: The Phase II technical objectives follow directly from the Phase I effort, where all tasks necessary for RF photonic receiver fabrication were demonstrated. The Phase II effort will pursue two major objectives: 1) further development of SEO100 EO polymer based chips, packaged devices and arrays in collaboration with University of Dayton (antenna designs), taking advantage of multiphoto ...

ABSTRACT: AdValue Photonics and University of Arizona propose to demonstrate the capability of fabricating wavelength division multiplexers (WDM) for high-power fiber laser applications. It is based on AdValue Photonics"unique fused fiber technology using large-mode-area (LMA) fibers. Both polarization-maintaining (PM) and non-PM LMA fiber WDMs will be fabricated. By the end of Phase I, two proto ...

ABSTRACT: Pulsed power systems are utilized in several application platforms ranging from fuel reforming to biomedical applications. While significant advances have been made in development of solid state technology based power systems, the need for faster pulse rates as well as higher voltage requirements have resulted in a need for developing novel pulse power sources capable of pulsing at freq ...
