We propose to develop a low SWaP, portable microwave Rb-87 cold atomic clock using pulsed coherent population trapping (CPT). The SWaP goal is to achieve a volume of

The primary goal of this proposed effort is to develop mid-wavelength infrared (MWIR) colloidal quantum dot (CQD)-based focal plane arrays (FPAs) to significantly reduce the cost of MWIR photon imagers. In order to realize this goal, it will first be nec

The proposed effort will extend existing proofs of concept and advanced research systems to: (a) provide an efficient, low-level, data-parallel runtime for graph processing on GPUs; (b) provide a high-level abstraction for writing graph analytics that are

Existing high-channel-count interfaces used to capture neural information from and to stimulate neural activity in tissues rely on transcutaneous connections to convey both information and power. These transcutaneous connections introduce a number of significant problems: limit patient comfort/mobility, increase infection risk, and significantly reduce the long-term system reliability. In this Pha ...

In order to maintain our nation’s technological superiority on air, sea and land, we must respond quicker to emerging threats and reduce the cost of major sensing platforms. Every DoD platform developed nowadays contains at least one sensor, whether it be RF, EO/IR, or acoustic. In fact, in a lot of recent developments, the platform is built around the sensor and exists only to support the senso ...

By any measure, the human hands and brain form a remarkable system for perception and manipulation. Of particular interest to us is the ability to perform tactual stereognosis: i.e., to identify objects by touch. In a landmark study, Lederman and Klatzky (1987) showed that stereognosis is subserved by a set of stereotypical “exploratory procedures” (EP) such as enclosure for shape, static co ...

This program proposes to demonstrate an ultra-low power design methodology and circuits for digital logic employing advanced dynamic voltage scaling (DVS) for asynchronous NULL Convention Logic (NCL) circuits operating in sub-threshold to super-threshold voltage regimes. The power supply voltages of logic block partitions will be independently set by on-chip voltage controllers based on the data p ...

Kyma Technologies, a leading supplier of low defect density GaN substrates, is teamed together with the three subcontractors at Princeton University, Lehigh University and Purdue University where some of the best lattice-matched quaternary (In,Ga,Al)N or ternary structures in the world have been produced, to propose the development of the world¡¦s first high-performance III-N quantum cascade las ...

The overall objective of the proposed project is to develop the feasibility of large format solar-blind focal plane arrays (FPAs) based on wide band-gap III-Nitride based optoelectronic sensor elements hybridized to silicon based read-out integrated circuits (ROICs). MP Technologies and the proposed subcontractor (the Center for Quantum Devices at Northwestern University) have already demonstrate ...

The objective of the proposed project is to demonstrate III-Nitride based terahertz intersubband quantum cascade lasers operating at near room temperature. III-Nitrides have a large band gap and band offset that has generated recent interest for the realization of short wavelength (1.55 um) telecommunications lasers. However, in addition to the large band offset that makes short wavelengths pos ...
