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 ...

State of the art Radiation Hardened by Design (RHBD) techniques must scale down in feature size for radiation effects in 45 nm processes, and also scale up in complexity to support radiation fault analysis of VLSI circuits. Recent access to commercial 45 nm CMOS Silicon-on-Insulator (SOI) technologies has increased the interest in this technology for rad-hard electronic applications due to the in ...

A back-illuminated planar InGaAs photodiode tested to have 95% quantum effiiency (QE) at 1550 nm, area greater than 1 mm2, low capacitance (125 MHz) will be improved. Although the existing Phase I device exhibited bulk material dark current generation better than commercially available devices, the sidewall-generated dark current was found to dominate the noise equiva ...

We propose to develop a commercially adequate, robust and perfomant OWL-based Integrity Constraint (IC) validation system with several innovations, including novel debugging and explanation support for data integrity errors; incremental and optimized validation of data integrity; and a unified system for validating structured, semi-structured, and semantic data. A rigorous and formal specification ...

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 ...

The objective of this research is prove the feasibility of automatically migrating radiation effects predicted in TCAD level tools to compact modeling tools. This transition will enable compact models that possess radiation effects to be quickly generated, which can then be used in circuit design activity. This "model-in-a-day" approach is a substantial improvement over the current ad hoc approach ...
