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 ...

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 ...

Recent advances in computing have produced special-purpose hardware comprised of vector processors streamlined for high-performance computations. Development of these devices, such as graphics processing units (GPUs) and the Cell Broadband Engine (Cell Processor), has been advanced by the videogame industry. In an effort to increase flexibility and enter new markets, vendors have increased platf ...

Wide-area networks are essential to productivity in commercial enterprises and military organizations. Reliability is difficult to achieve because wide-area networks, such as the Internet, are built from many autonomously configured component networks. Today there exists a large gap between the intended design of a network and the implementation of that design. This is because complex network poli ...

Lattice Block Materials, or LBM for short, are a class of materials comprised of an open structure of ligaments arranged in a regular truss like structure that is three dimensional. A basic unit cell is comprised of a square based pyramid skeleton (just the corners, called nodes, and the edges, called ligaments). These cells are connected in all directions to form a larger lattice like structure ...

Vaporcor LLC is developing a very high altitude (~90 kft) aircraft propulsion engine capable of meeting the stability, reliability, and environmental requirements suitable for use on a VHALE aircraft with 12-20 hour endurance that must be stored for months. Vaporcor’s VHALE engine implements a closed loop Rankine thermodynamic cycle using super-critical CO2 (S-CO2) as the working fluid. The Ra ...

An existing low-cost FPGA-based processing platform will be demonstrated with fiber-coupling to single-photon detectors, to perform photon-arrival time stamping with

A stable, well characterized InGaAs materials growth and photodetector fabrication process will be used to fabricate matched photodiodes optimized for balanced homodyne detection. The 1-mm-diameter p-i-n photodetectors will be manufactured back-illuminated with a 5-micron absorber, allowing residual light to reflect off the front-side metal to make a double pass through the active layer. Ultra-hig ...

Voxtel has demonstrated efficient high-speed photon counting with thresholded linear-mode avalanche photodiode (APD) receivers using multi-gain-stage InGaAs/InAIAs APDs. In contrast to Geiger APDs, thresholded photon-counting linear APD receivers are thought not to suffer afterpulsing, and can support maximum count rates (MCR) up to 2 or 3 orders of magnitude faster than Geiger APDs. However, the ...
