In this SBIR effort we will develop a high-power, high-speed photodiode (PD) receiver optimized for operation at 1 micron wavelength based on collaboration with Dr. J.C. Campbells research group at the UVA. Demand of such photonic receiver arose from the urgent need of high performance microwave photonic links that replace the conventional metal cables for better SWaP, immunity to EMI and broader ...

In Phase I, UTC successfully demonstrated the ability to build 3D, high-to-low-Z graded alloys (GA) with Selective laser melting (SLM) additive manufacturing (AM) techniques. In Phase II, UTC will fully automate and scale-up the GA AM process, and work with Lockheed Martin Corp. (LMCO) and Southern Research (SR) to fully characterize the process so components intended for use on LMCO missile syst ...

Our proposal specifically addresses the stated requirements of the solicitation; we will develop and deploy tools, methods, and models for enhancing the mission assurance of our nations embedded computing systems. As designs continue to progress in com

In this proposal, AlphaSense, Inc. (AI) and the Oklahoma State University (OKState) detail the development of a novel Cavity Enhanced Terahertz Absorption Spectrometer (CETAS). Key innovations of the proposed system include: a) the use of a small Whispering- Gallery- Mode (WGM) cavity to achieve very long pathlength; and b) the integration of the WGM cavity with the conventional pulsed and continu ...

In this proposal, AlphaSense, Inc. (AI) and the University of Michigan (UM) detail the development of a compact, portable, and low cost in-process weld defects detection system. Key innovations of the proposed system include: a) weld defects monitoring based on plasma emission characteristics; b) use the electron temperature of the plasma as an indicator of the weld quality, c) use multiple plasma ...

Extreme weather conditions with degraded visibility severely reduce the performance of existing imaging technologies to detect rockets, artillery, and mortars (RAM) on a battlefield. To meet the Army need for improved sensor systems that perform well in such conditions Optonicus has developed a fiber-array illuminator multi-sensor all-weather tracker (FAST) system that includes a gated imaging sys ...

The automotive and aerospace industries use topology optimization to minimize structural weight while satisfying functional constraints. However, the industry-standard fictitious material or density approach has been less effective when applied to physics beyond simple structural mechanics. Known issues include: failed numerical convergence or so-called gray material in computed optimal designs, n ...

Existing filter technology does not suit the mechanical and electrical needs for use in expendable buoy systems. Current diplexer designs do not provide adequate rejection of the high power transmitter signal within the receive channel within the specified size, weight and acceleration constraints required for the Navy Buoy System. The proposed research includes the analysis and simulation of a h ...

A novel carbon nanotube ceramic composite is proposed herein to protect organic matrix composite materials, specifically munition relevant composite structural aeroshell materials, from directed energy, nuclear EMP, and nuclear particle effects. This CNT-
