Next generation vector vortex waveplates for astronomical coronagraphs

The objective of the proposal is advancing the technology of vector vortex waveplates (VVWs) into: novel spectral ranges that have been practically prohibited by fabrication tolerance and even fundamental issues; broader spectral bandwidths wherein a single VVW could be used for coronagraphs developed for vastly different parts of spectrum; novel, highly robust VVW architectures that would eliminate or, at least, will dramatically reduce the effects of fabrication errors and ambient conditions on device performance; polarization-insensitive VVWs; reduce size and weight of coronagraphs by providing VVWs with other optical functions and integrating them with other multifunctional planar optical components of 4G optics; reduce cost levels wherein the technology becomes available and affordable for low-cost applications and missions.

This is early/mid-stage (TRL 5) — 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.
