The ARMY needs active protection using a UV and IR dual band focal plane array (FPA) to detect and track hostile fire so that targets can respond and avoid incoming rounds. The objectives of this effort are to determine the requirements of an uncooledUV/IR FPA for active protection and demonstrate feasibility of integrating UV and IR detector arrays with the readout integrated circuit (ROIC). In ...

We will develop novel acousto-optic devices for use in the UV using the new material Barium Borate (BBO) which not only has the required UV transparency, but a unique combination of acoustic and optical properties. The capabilities provided by these new UV AO devices are ideally suited for optical addressing arrays of trapped ions with focused spots from appropriately tuned UV and visible lasers t ...

The Army has identified solid oxide fuel cell (SOFC) power systems as a potential solution to a variety of power needs ranging from roughly 0.1 - 100 kW. Reformed JP-8, the Army logistics fuel, can be used as the feed, but the fuel sulfur content must first be reduced to 10 ppm. We plan to test a novel ultrasonic slurry reactor as part of a compact desulfurization process for treatment of sulfur ...

This STTR program proposes to exploit the tremendous benefits that could be offered by the development of ultra fine grain steel alloys for application to the production of high performance components for military rotorcraft applications. A severe plastic deformation technology based on isothermal forging technologies will be explored here. The goal is to demonstrate a practical, production leve ...

Leveraging Agiltron"s industrial leading developments and production of Raman instruments, external cavity laser and nonlinear optical components, we propose to develop a new class of high performance compact deep ultraviolet (UV) laser for Raman spectroscopy. The approach is closely coupled with recent progress in GaN blue laser and external resonator enhanced second harmonic generation (SHG) to ...

In this STTR program, technology created at the University of California at Santa Barbara (UCSB) to fabricate silicon photonics based integrated laser devices, including wafer bonded gain elements, will be utilized to develop ultra-coherent integrated laser devices that are widely tunable. Novel laser designs developed by Morton Photonics, taking advantage of ultra-low loss microresonator based f ...

Spontaneous emission is a quantum mechanical process that represents the main source of phase noise in state-of-the-art semiconductor lasers, limiting their coherence, and their suitability for high-speed communication and sensing applications. This proposal aims to develop ultra-high coherence semiconductor lasers on the Silicon/III-V platform with a quantum linewidth of

The proposed project will demonstrate high-frequency (0.5 5 GHz) operation of novel 2-dimensional semiconductor molybdinum disulphide (MoS2) based field-effect transistors. Our project will focus on innovative growth startegies for large-area growth of MoS2 along with novel device design methodologies which will consider the tradeoffs between monolayer and multilayer device designs for high-frequ ...

Current scene projection hardware is challenged to simultaneously meet the requirements for high peak temperature (> 2000K), high resolution (> 1Kx1K), response time < 1 ms, cryogenic and temporally uniform photon flux. MEMS, Resistor arrays, liquid crystals, and photonic crystals all suffer in one or more areas. MEMS suffer from flicker and low dynamic range. Resistor arrays suffer from low frame ...

ALTAIR Center proposes to develop a new class of tunable terahertz laser sources based on an active laser material fabricated from spherical semiconductor nanocrystals (quantum dots) incorporated into an optical medium transparent in terahertz-frequency range. Due to the strong Stark effect, recently discovered in semiconductor nanocrystals, the transition frequencies can be shifted by an applied ...
