ABSTRACT: Silicon-based lasers/detectors have long been desired for owing to the possibility of monolithic integration of photonics with high-speed Si electronics and the aspiration of broadening the reach of Si technology by expanding its functionalities well beyond electronics. The goal of this project is to first develop high quality SiGeSn material and then use it to demonstrate prototype opt ...

ABSTRACT: This document presents Optical Sciences Corporation's SBIR technology transition proposal to complete development of an advanced Cryogenic-Vacuum Compatible Infrared Scene Projector (CVC IRSP) for Wide Field-of-View (WFOV) space sensor testing and to integrate the CVC IRSP into a government owned space simulation chamber. The CVC IRSP will be capable of projecting complex scenes w ...

The vast majority of injuries in recent military conflicts have been inflicted by improvised explosive devices (IEDs) causing brain, extremities and genital-urinary injuries. Advanced computational models of IED blast physics and human body injury biomech

ABSTRACT:Nonvolatile memory (NVM) technologies are a critical component of modern satellites.These NVM chipsets perform tasks ranging from storing mission-critical boot code to large multi-gigabyte mission data recorders.This requirement for high-density NVM has shifted focus on to commercial CMOS FLASH.FLASH technologies are capable of high-density devices, compared to resistive or phase-change t ...

ABSTRACT:The LWIR spectrum is well suited for moderate- to long-range free space communications because of its atmospheric window and low scattering by dust, haze, precipitation, and fog. The recent impressive laser development of QCLs is poised to provide the high speed LWIR transmitter for such a free space communication system; a corresponding advance in LWIR detectors is needed to enable the h ...

ABSTRACT:In this work, an ephemeral security technique for keying military GPS receivers will be developed. This work will not modify the existing GPS cryptographic structure, but rather develop an overlay for providing keying information to a receiver in a manner that makes all security information ephemeral, eliminating the permanent storage of CPI within the receiver. Existing and emerging batt ...

ABSTRACT:There is a need for a moderate resolution, high speed, radiation hardened (RH) Digital to Analog Converter (DAC) to support new satellite developments. Scientic proposes to develop a high speed, radiation-hardened DAC to be produced on-shore in a trusted semiconductor foundry to meet the data conversion needs of the US Air Force (AF) and other military and aerospace system developers. To ...

ABSTRACT:As weapon velocities increase significantly in the coming years, driven by reduced response times and by the strength of materials in target structures, the already-significant shock loads on explosive payloads and fuze components will be greatly exacerbated. Given that the integrity of the payload and fuze components is critical to proper weapon functioning, it is imperative that solutio ...

ABSTRACT:Type II strained-layer superlattice (SLS) materials are predicted to have much lower Auger recombination rates than those of HgCdTe, leading to lower dark currents; however, they are limited by Shockley-Read-Hall recombination via defect states near mid-gap. Hydrogenation is a technique that has proven to be effective in electrically passivating defects in various semiconductor-based devi ...

ABSTRACT:nou Systems proposes an innovative analysis and test methodology for testing space-based high-resolution wide field-of-view (WFOV) focal plane arrays (FPAs). Current space sensor test facilities are incapable of fully testing state-of-the-art high-resolution WFOV sensors without infrastructure modifications. The test methodology described in this proposal focuses on testing only a subset ...
