This project address the fabrication of solar blind detectors from the MgZnO material system. Both MBE and MOCVD material growth techniques will be used for deposition of the required material layers. Simulation software we be used to aid in the design of the photodetector structure. Devices will be fabricated from the grown structures and their electrical and optical characteristics determined.

To maximize our military effectiveness, the US must maintain an asymmetric advantage with its next generation technology and weapons. Directed energy weapons such as lasers are one class of weapons in which the US can maintain this advantage by also developing advanced laser defense technology. This proposal builds on our Phase I results using reflective optical limiter coatings which mitigate las ...

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 ...

Missiles experience a wide range of thermal and mechanical environments due to the large variety of flight profiles. Since the missile radome is often the aerodynamic leading edge, it undergoes significant thermal and mechanical loading. The radome must survive the dynamic pressure loading, thermal shock and environmental erosion from airborne particulates (rain / sand) while performing as an elec ...

A 3-sided pyramid wavefront sensor (PWFS3) suitable for use with a range of telescope sizes will be built. Laboratory testing will be carried out at the University of Arizona to verify functionality and performance relative to a Shack-Hartmann WFS (SHWFS). HartSCI's numerical models will be used to create realistic synthetic data from the PWFS3, PWFS4, and SHWFS that can be directly compared with ...

The overall technical objective of the Phase II effort is to develop a FUN3D-based adjoint framework using the Non-Intrusive Least Squares Shadowing (NI-LSS) for sensitivity analysis of complex configurations when exposed to buffet loads produced by chaotic flows. The FUN3D-based adjoint framework will be capable of generating buffet loads sensitivities with respect to both shape and sizing design ...

The objective of the proposed effort is to demonstrate robustly-engineered stable vertical-external-cavity surface-emitting laser (VECSEL) sources of 20 W at 589 nm and 10 W at 1141 nm with narrow linewidth matched to a single velocity class of mesospheric atomic sodium for guide star application. A scalable architecture is realized by employing multiple VECSEL devices in one resonator, thus ...

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 ...

ABSTRACT: The overall technical objective of this Phase II effort is to develop computational tools for computing response sensitivities of parametric multi-disciplinary air vehicle systems that exhibit nonlinear dynamic behavior for use in gradient-based optimization, smart sampling, uncertainty quantification, and risk assessment. To this end, the ZONA/MIT team will extend the 2-D ZEUS time-dom ...

SIFT proposes Network Enforcement Using TRansactONs (NEUTRON) a dynamic fine-grained network enforcement policy design that captures network dependencies. NEUTRON closes the knowledge gap between mission needs and observed network traffic to increase mission network awareness. Then using that knowledge develops a revolutionary security enforcement policy based on network transactions. It reduces t ...
