ABSTRACT: This program targets development of a high-performance thermoelectric (TE) cooler with a figure-of-merit, ZT>3, which greatly exceeds currently available technology. The cooler is fabricated using Group II-VI compound semiconductors, i.e. HgCdSe or HgCdTe, using a low dimensional structure know as a"superlattice"(SL). The proposed TE coolers will operate at temperatures ranging from 5 ...

ABSTRACT: This project aims to develop a Short Wave Infrared band image projector to provide real time detector stimulation with high dynamic range. Our emitter technology is based on GaInAsSb quaternary semiconductor LED arrays hybridized to CMOS read-in integrated circuits. This project leverages read-in circuit design and control electronics that were developed under SLEDS - a longer wavelengt ...

In the proposed effort, we will leverage this extensive experience and capabilities to realize a frequency agile mmW radiometer that can cover the range of DC-110 GHz and can be scaled to DC-200 GHz under Phase II. Ours is a photonic system that multiplies and up-coverts a low-frequency reference signal onto an optical carrier (laser) using EO modulation, then uses the modulation sidebands to inj ...

ABSTRACT: In this SBIR effort we will develop a packaging process and demonstrate (Phase I) a prototype of high power Photodiode (PD) that has a normal incident, pigtailed fiber input and a coaxial RF output that operates from DC to>60GHz. We will apply and extend (Phase II) the aforementioned packaging process to single PD, balanced PD and array of PDs that work from DC through entire W-band. De ...

ABSTRACT: there is a clear need for a radically new interconnect architecture that minimizes the routing delay through the backplane to enable increased performance, reduced costs, and faster time to market. To this end, we propose the development of a space compatible optically interconnected backplane with reconfigurable routing fabric. By removing the electrical interconnections between logi ...

ABSTRACT: Accurate prediction of part performance/reliability is at the core of health management of air vehicles and of supply chain management. Methodologies are needed to accurately predict/evaluate parts performance/reliability with compounding problem criteria/factors for early corrective actions and acquisition of aerospace parts. Accurate problem part (bad actor) identification and resou ...

The Defense Threat Reduction Agency (DTRA) and the U.S. Strategic Command Center for Combating Weapons of Mass Destruction (SCC-WMD) requires transformational materials technology to support the intelligence, surveillance, and reconnaissance (ISR) of personnel and materials associated with weapons of mass destruction (WMD) development, manufacturing, and proliferation. Voxtel, Inc. proposes to fa ...

Unmanned vehicles are becoming an increasingly valuable tool within the Department of Defense, and related technologies are beginning to appear in commercial systems. As their utilization grows, these unmanned systems will become a significant target for cyber attack. Indeed, existing Defense Department unmanned aerial vehicles (UAVs) have already been subjected to attack by various adversaries. ...

ABSTRACT: In this Phase II SBIR, a Voxtel Inc. led team will develop a lightweight small unmanned aircraft system (SUAS) delivered payload, including targeting and fire-control sub-system, taggant dissemination hardware, and taggant reservoir, that is capable of covertly delivering optical taggants. Because the performance of auto-pilots and video trackers is limited by SRPA system constraints, t ...

ABSTRACT: To increase the performance of current and next-generation imaging spectrometers for military applications, in this Phase II SBIR effort, a flexible readout integrated circuit (ROIC), optimized for hyperspectral imaging (HSI) will be developed with enhanced capabilities. The ROIC features a 1024 (spatial) x 512 (spectral) format, with 20 micron pitch pixel elements, and has been develop ...
