Completed TRL 3 (started at 2, targeting 3)
We propose follow-on development for photonic integrated circuit (PIC) that includes all essential laser metrology functions necessary for active alignment of multi-segmented telescopes represented by LUVOIR. This work would focus on packaging and testing developed PIC from our FY22’s IRAD/CIF or a PIC deliverable from an in-house ACT LIDAR project through collaboration. The performance of these PICs would be evaluated by frequency stabilization with gas cell, phase locking between two lasers and laser metrology demo. These results would be compared with commercial lasers running the same tests to evaluate PIC edge sensor feasibility.
LUVOIR is our primary targeted customer, but any other segmented mirror telescope missions where precise metrology alignment is needed would benefit from this work.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — 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.
