The overall objective of the proposed Phase II STTR program is to continue optimization of properties already obtained during Phase I which established the feasibility of concept to multi-functionality for BMI polymer matrix composites along with structural capability. Throughout this 2-year effort, it is proposed to seek optimization of the composite properties. The goal is develop and demonstrat ...

An increasing amount of information comes in the form of streaming text: news media, email, and even human conversation. Creating insight from streaming text has been challenging though, because current knowledge discovery systems depend on expert analysts to move from simple data to actionable knowledge. In order for such systems to be used outside a small cadre of experts, they must incorporat ...

Semiconductor amplifiers and lasers are pervasive as critical components in modern day military and commercial technologies. High quality semiconductor wafer growth can now produce heterostructures of very high quality with stoichiometrically correct growth of individual mono-layers. Despite these significant advances in MBE and MOCVD growth technologies, a critical void remains in predicting the ...

QuantTera is developing a new class of silicon based-quantum-well near-infrared lasers using group IV semiconductor materials for photonic integrated systems. The uniqueness of this project lies in the development of a strained quantum well active region, which can be tuned to various laser emission wavelengths in the near-IR. Further more this laser will be integratable to existing electronic d ...

The proposed work addresses an opportunity to develop a portable, tunable backward wave oscillator (BWO) for room temperature generation of terahertz radiation. The approach combines microfabricated photonic crystal waveguide circuits with state-of-the-art electron guns to achieve the efficiency needed for portability. The initial devices will target the 1 to 2 THz range, though the approach can b ...

The ZONA Team proposes to establish an Aero-Servo-Propulso-Elastic (ASPE) methodology as a conceptual design/analysis tool for the stability and control of a Single Engine Missile (SEM) model, representing a generic hypersonic wave-rider with airbreathing/scramjet engine. With body flexibility included, the SEM formulation considers all physical components in order to capture the underlying physic ...

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: Due to scarcity of spectrum, Dynamic Spectrum Access (DSA) becomes a needed technology to improve the utilization of electromagnetic spectrum for DoD satellite communication. However, current DSA approaches are developed for terrestrial communications without addressing the unique challenges for SATCOM environments such as error-prone spectrum sensing, high mobility, and large coverage. ...

ABSTRACT: Coordinating and sharing information across multi-level security (MLS) networks are of great interest in many military applications. However, it is very challenging to accomplish those goals due to the heterogeneous security classifications of different network domains. The recent proposed cross-domain solutions (CDS) provide initial steps to make such applications possible. However, th ...
