The ability to rapidly detect, identify and monitor chemical agents remains a challenge of significant importance to the Armed Forces. Existing chemical sensing techniques have shortcomings that inhibit widespread implementation. To address this situation, Ryon Technologies is developing a portable instrument that is based on Rydberg Fingerprint Spectroscopy (RFS) in combination with mass spectrom ...

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 ...

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 ...

A model for structural health measurement is desired that is capable of assessing the accumulated damage and remaining useful life of components post-flight. This model will eliminate the need for load tracking during flight and prevent the additional weight and complexity of components utilized during flight. Safe is partnering with researchers at University of Memphis for this work to relate the ...

Combustion instability, or screech, occurs in many modern gas turbine systems, and is due to the complex physical coupling of the acoustic resonances in the combustion chamber with fluctuations in the heat release of the combustion process. These instabilities can produce large pressure fluctuations that can be severe enough to damage engine hardware. Next-generation gas turbines will increase the ...

Yardney will design and develop a lightweight, safe, reliable, and cost-effective aircraft battery with improved thermal design and the use of active cooling techniques. As a novel part of the battery design, Yardney will investigate and implement high performance electrodes using three dimensional (3D) micro-porous current collectors, safer thin metal case cell design, a micro-channel heat pipe t ...

This proposal examines innovative approaches and technologies that can be used to evaluate legacy models and simulations, determine the feasibility of porting them to multi-core simulation environments, and enable the legacy model capabilities to efficiently execute in such multi-core environments. We will employ Discrete Event System Specification (DEVS) Simulator architectures to support highly ...

Few-cycle mid-infrared lasers are highly demanded for a variety of practical applications. NP Photonics and University of Arizona propose to develop a wavelength tunable and power-scalable optical parametric laser system at 8-12 micron capable of producing collimated few-cycle pulses with pulse energy>100 microJoule. In this phase I program, we will design the whole laser system and do a feasibil ...

We propose a wearable, dual-use neurotechnology device. The Personal Brainwave Headband, driven by tablet or smartphone, is designed for noninvasive closed-loop acoustic stimulation, to permit improved circadian regulation. It will measure brain electrical activity from scalp overlying four key sectors of cortex, perform high-resolution spectral analysis of the signals, and use software algorith ...
