In this STTR program, Photonic Systems Inc. and Prof. Jacob Khurgin at Johns Hopkins University propose novel optical external and internal fiber cooling approaches to efficiently cool the high power GaN microwave amplifier. The external cooler is a single end, square-shape, Yb:ZLAN fiber with high reflection (HR) coated surface which can attach to the amplifier surface and create a cold spot at t ...

Future naval operations are expected to make extensive use of unmanned vehicles to support a range of operations, including intelligence gathering, mine warfare, force protection, and anti-submarine warfare. Current unmanned systems are typically controlled remotely by an operator who directly manipulates a control interface for the vehicle. The effectiveness of this approach is obviously limited ...

The implementation of structural health monitoring (SHM) systems into naval applications has been hindered due to component quantity, including sensors, power/communication cables, and acquisition/computation units, as well as data quality. Particularly for large-area applications such ship hulls, complexity of implied system infrastructure can be impractical, and data can be worthless with attenu ...

SI2 Technologies, Inc. (SI2) proposes an innovative solution to the Navy’s need for wideband antennas to support naval ships and Marine Corps’ vehicle communications, electronic warfare (EW), and radar functions. SI2 will develop efficient, broadband, metamaterial antennas for operation in the VHF-UHF frequency range. These antennas will initially be designed for integration with the composite ...

Busek Co. Inc (Busek) and Massachusetts Institute of Technology (MIT) propose to develop the design of a photon actuated, ultrafast carbon nanotube (CNT) field emission cathodes for high-power electron beam accelerator sources. The cathode will be based on massive arrays of Vertically Aligned Carbon Nano-Fibers (VA-CNFs) that are individually controlled by a vertical ungated field effect transisto ...

Electromagnetic launchers or rail guns are a key component of the Navy’s all-electric ship of the future, but they lack the durability required for repeated firings. TDA Research and the University of Nevada, Reno (UNR) are developing a tough, durable and conductive refractory metal coating that will protect the copper alloy conductors (rails) from the extreme heat and wear conditions inside the ...

Physical Sciences Inc. (PSI) and Duke University propose to develop a hybrid, multifunctional, ultraviolet (UV) beam conditioner intended for laser beam switching, deflection, and frequency shifting for quantum computing applications. The beam conditioner consists of three functional blocks, separating the technology for frequency control, fast amplitude control, and electronic beam shuttering int ...

Recent advances in THz-source stability, power and practicality have opened the door for active THz imaging in both commercial and military settings. AEgis is teaming with U Buffalo to develop a THz detection device that utilizes classical rectification effects in semiconductor point contacts (SPCs) to achieve response in the 1 to 10 THz range and is capable of operating at temperatures over 150 K ...

LADAR light reflection from a target is highly dependent of the spectral reflectivity and texture properties of the surface. Such dependencies could be exploited for target recognition based on surface characterization with appropriate imaging conditions and processing algorithms. Target surface light reflection is characterized by the Bidirectional Reflectance Distribution Function (BRDF), which ...

Mayflower Communications has partnered with the Boston University Hearing Research Center to propose novel techniques for speech enhancement in reverberant environment based on advanced auditory modeling of higher-level processing in the human auditory brain. Speech enhancement or noise suppression has been an area of active research for well over three decades. State-of-the-art single-microphone ...
