Sb-based III-V semiconductor Type-II superlattice (T2SL) materials with band structure-engineered device architectures are groundbreaking for infrared detectors and focal plane arrays (FPAs). T2SL FPAs have become very attractive candidates for various MDA/DOD sensor platforms including air, space, ships, and missiles. T2SL wafers, the starting materials of FPAs, are grown on large substrates usin ...

American Energy Technologies Co. (a woman-owned small business concern of Arlington Heights, IL), will be joined by subcontractorAdvanced Technology Laboratories of Lockheed Martin Corp. (St. Paul, MN) in order to develop and fully furnish functional prototypes of two anti-corrosion technologies with the goal to deploy them in a variety of MDA-owned equipment platforms. The first technology is a t ...

There is a need for tactical IMUs with better accuracy than the state of the art. We at Digital Optics Technologies (DOT) have been developing the superluminal ring laser gyroscope (SRLG) and superluminal ring laser accelerometer (SRLA). During Phase I of this program, we developed a new design that serves both functions simultaneously, a superluminal ring laser gyroscope and accelerometer (SRLGA) ...

CU Aerospace (CUA) and team partner Lockheed Martin Space (LMS) propose to develop a low-cost and more efficient cryocooler cold head designed for 5 W cooling at 77 K, and to begin the process of certifying CUA’s innovative approach to provide CUA-built cold head subassemblies to LMS in order to reduce cryocooler costs. Materials and materials processing expertise at CUA will be used to investig ...

Sivananthan Laboratories (SL) with the University of Iowa as the STTR partner, proposes to develop metasurface-coupled type II superlattice (T2SL) LWIR detectors that are predicted to outperform HgCdTe detectors. We developed in Phase I fundamental understanding of metasurface-coupled T2SLs, likely performance, and issues related to scaling up device structure to form arrays for LWIR imaging. In P ...

We propose a large-format LWIR HgCdTe Focal Plane Array that can perform rudimentary signal pre-processing and increase pixel well dynamic range, thereby elevating seeker abilities to acquire, track, and discriminate enemy targets. This approach, supported by Lockheed Martin and BAE Systems, is based on a novel differential dual pixel design using pairs of adjacent pixels each connected in an inv ...

Diesel engines remain critical to global economies, but are under threat from increasingly-stringent emissions regulations. Many alternatives, like spark-ignition and electric vehicles, sacrifice some of the performance or range benefits of Diesel-style operation. This creates a market need for technologies that can maintain Diesel engine performance while remaining decoupled from the dirty emissi ...

Infrared photon sensors presently available for THAAD applications, with a cutoff wavelength ~8 micron, are based on HgCdTe. These suffer from a high non-uniformity and thus a high focal plane array cost. The most promising alternative is III-V compound semiconductor superlattices based on arsenides and antimonides, such as type-II InAs/GaSb superlattices, which are expected to exhibit higher qu ...

End-to-end communications systems are often so complex that system designers have difficulty keeping track of the constraints, trades, interface requirements, and interdependencies among components. The Communications System Taxonomy (CommTax) and Toolkit development continuation proposed herein represents further refinement of an innovative tool that MorganFranklin Corporation and its partners, A ...

In the Phase I program, EPIR Technologies successfully developed lapping, polishing, and cleaning protocols for 2 cm x 2 cm Cd0.96Zn0.04Te wafers for the molecular beam epitaxial (MBE) growth of HgCdTe. The implementation of a custom engineered EpiTEK™ crystal polishing machine in this Phase I program allowed EPIR to establish process limits for reproducibly polishing CdZnTe to MBE standards. Th ...
