About the NASA Postdoctoral Program

The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.

Sensor systems based on high performance infrared (IR) detectors have made significant contributions to NASA’s Earth Science (e.g., observables related to Surface, Biology, and Geology) and Planetary Science missions (Io Observer, Lunar, Uranus), and to science in general. IR detectors are ubiquitous to almost all areas of measurement, and detector arrays flown on space missions have provided exquisite visual and scientific images, instrumental in advancing our understanding of our home planet and the universe around us.

Our goal is to pursue the development of emerging detector technologies which promise extensions in sensitivity, resolution, array size and other figures of merit relevant to the full set of NASA Quests, while simultaneously decreasing their size, weight and power requirements (SWAP) so critical for space missions, as well as their cost.

Large detector arrays in the visible and near IR have been developed that come close to the physical limits in terms of quantum efficiency (QE) and dark current. Future work on detector materials will extend this performance into the long-wavelength IR (LWIR). Artificially fabricated heterostructures are providing improved performance over bulk LWIR materials, and further work is needed to fully exploit this approach for high QE and low noise in large LWIR arrays.

Significant enhancement is also possible in the design and fabrication of digital read out integrated circuits (DROICs) for space instruments that affect focal plane array (FPA) signal to noise, dynamic range, and speed. Novel in-pixel DROIC architectures avoid signal saturation when imaging high-dynamic-range sources and minimize instrument SWAP. Other key advances important to pursue in FPA design are the development of novel approaches to achieve single photon counting, such as Avalanche Photodiaodes (APDs) in mid- and long-wavelengths.

The integration of nanostructured flat lens technology and other meta surfaced components such as filters and polarize rs into FPAs is also an important area to increase performance and reduce SWAP.

Research objectives may include:

• Perform trade study to determine the best approach for the detector using advancements such as III-V heterostructure engineering
• Determine key metrics for success such as spectral range, SNR, operating temperature, pixel uniformity, operability, etc.
• Develop the necessary analysis and simulation to justify that the proposed approach has a reasonable chance of meeting the key metrics
• Develop and demonstrate proposed approach that is consistent with the analysis/simulation results. This include test detectors
• Analyze how environmental variables such as vibration, radiation environment, etc. may limit the usefulness of these IR detector in space environments
