Space-variant Pancharatnam-Berry Phase Metasurfaces for Segmented Aperture Coronagraphs

Completed TRL 4 (started at 3, targeting 4)

Description

Develop geometric phase masks optimized for segmented aperture vortex coronagraphs, achieving extreme broadband starlight suppression and high exoplanet light throughput, enabling exoplanet spectral characterization. Demonstrate segmented aperture starlight suppression with a reflective pupil-plane GPMS on a coronagraph testbed with active wavefront control

Benefits

Segmented aperture coronagraphs achieving broadband 10^(−10) contrast with a factor of 2 improvement in exoplanet throughput possible over existing state of the art achromatic apodized vortex coronagraph designs

How to get involved

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
