Photon-Counting Integrated Circuit (PCIC) Photodetector Arrays

Completed TRL 4 (started at 3, targeting 4)

Description

Technological improvements in sensors available to NASA have a significant cross-cutting impact for an array of NASA instruments measuring over a broad range of the electromagnetic spectrum. Improvements of detector performance would cause a significant shift in capability. The commonly used avalanche photodiode (APD) boosts the signal level of input optical power. However, high avalanche excess noise and extreme sensitivity to bias voltage makes it very difficult to achieve high gain or gain uniformity across an APD 2-D focal plane array, let alone the Geiger recovery time. The PCIC is an enabling technology potentially providing for greater detector sensitivity in a wide range of thermal and radiation environments.

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.
