In this Phase II SBIR effort we will dramatically reduce the size, weight, and power requirements of a passive millimeter wave imaging system based on optical upconversion. To this end, we will integrate custom silicon-germanium low noise amplifiers that have been designed to efficiently couple with our high performance lithium niobate upconversion modules. In Phase I we analyzed the design requ ...

Commodity graphics processing units (GPUs) offer tremendous computational throughput for relatively little cost. They have been shown to outperform microprocessors in the important metrics of FLOPS/dollar, FLOPS/Watt, and FLOPS/unit space and have already been applied to a wide range of numerically intense problems. In Phase I of this project, we demonstrated their potential to enhance complex C ...

Under the DARPA sponsored Naval Advanced Amorphous Coating (NAAC) program, a novel, thermal sprayed amorphous metal coating has been developed. Such a coating has demonstrated superior mechanical and corrosion resistance properties. Although the coating is designed to be life-of-ship, the application and operational conditions may compromise the integrity of the coating. For example, the applicati ...

In this SBIR effort we will design (Phase I) and demonstrate (Phase II) an integrated silicon electronic-photonic upconversion receiver that when used with our photonic backend will allow for a highly sensitive, real-time, and economical millimeter wave (mmW) imaging system. The development of this chip leverages recent progress in CMOS and SiGe HBT high speed analog circuit design and integrates ...
