The recent performance increases in graphics processing units (GPUs) have made graphics cards an attractive platform for implementing computationally intense applications. With their numerous parallel computational pipelines and SIMD architecture, modern GPUs can outperform high-end microprocessors by one to three orders of magnitude, depending on the problem. Most work to date at EM Photonics a ...

NASA's next generation of x-ray observation missions require x-ray calorimeters with superior energy resolution. Semimetallic HgTe has already proven itself as an excellent soft x-ray absorber material due to its low heat capacity. Hg0.834Cd0.166Te was shown in Phase 1 to have a heat capacity superior to that of HgTe. Hence Hg0.834Cd0.166Te-based microcalorimeter arrays are expected to have an ene ...

The objective of this proposal is to study and demonstrate novel GaAsNP/GaP/AlGaP technology for use in extreme photovoltaic (PV) energy conversion. NASA and the scientific community are interested in solar missions that go as far as Saturn or even into near sun conditions. Such missions present a challenging problem for PV technology. In addition to the requisite high efficiency and reduced so ...

The goal of this Phase II project is to deliver an integrated L-band transmit/receive (T/R) module which will be fabricated from a GaAs-based combined HBT/PHEMT epistructure. The T/R module will consist of a power amplifier, a low noise amplifier, and two switches. The performance goal for the low noise amplifier is 30 dB gain with a less than 1.0 dB noise figure. The performance goal for the p ...
