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:The objective of the proposed research is to investigate the feasibility of constructing a 27 cm diameter infrared (IR) source with a calibrated output radiance that is as accurate as the current state of the art, yet fits in a volume that is 10 times smaller than a blackbody of comparable aperture size and accuracy, and outputs only half the power. The required effective emissivity of 0. ...

ABSTRACT:To address the challenges posed by operating in accordance with complex federal acquisition regulations that discourage nontraditional providers from partnering with the government in emerging markets, ARiA LLC, a research-and-development firm that develops machine-learning and cognitive-computing software for commercial and government use, in collaboration with CPJ, a nonprofit nonpartis ...

ABSTRACT: The goal of head-worn display systems is to increase situation awareness and reduce operator workload. The urgent need is for higher image resolution and lower system latency, while meeting constraints on head-borne weight and power. Current processor solutions cannot meet increased requirements. The challenge is that power consumption is proportional to the amount of data being handled, ...

NASA has a need for electronics that can support proposed flagship missions such as a Venus surface lander. Devices that can operate at temperatures of up to 500?C are desired. Ozark IC and its partner, the University of Arkansas, have created the world's largest known library of CMOS silicon-carbide (SiC) analog and mixed-signal circuits, intellectual property (IP) and packages that can operate ...

Commercial silicon carbide (SiC)-based photonic sensors typically use p–i–n photodiode and reversed-biased Avalanche Photodiode (APD) detectors. These state-of-the-art SiC photodioides use the wafer substrate as one node of the device, thereby making monolithic integration of the device with control or analysis circuitry difficult, if not impossible. Ozark IC's new (patent pending) phot ...

AeroMancer Technology proposes to develop a 3D Lidar Global Airspeed Sensor (3D-GLAS) for remote optical sensing of three-component airspeeds in wind tunnel applications. Current methods of non-intrusive airspeed measurement include techniques such as Laser Doppler Velocimetry (LDV), Particle Imaging Velocimetry (PIV) and Doppler Global Velocimetry (DGV). However, some common drawbacks of all thes ...

The objective of this proposal is to develop and commercialize a high reliability, high temperature smart neutron flux sensor for NASA Nuclear Thermal Propulsion (NTP) systems. Arkansas Power Electronics International (APEI) and International Femtoscience (FemtoSci) technology offers the following: (1) 600+ degC ambient operation of a full wireless smart sensor system (2) Extreme-environment elec ...
