Field Programmable Short Wave Infrared Photodetectors

SK Infrared is proposing an SBIR Phase II Extension Option (Phase II-E) to advance the development of state-of-the-art in short wave infrared (SWIR) detectors based on pin mode and linear mode avalanche photodiodes (PIN-APD) to meet NASA’s needs for advancements in beaconless pointing and star tracking technology. To transition and mature this technology from the research conducted in Phase I and Phase II, SK Infrared will develop a mid-format focal plane array (FPA), by refining the heterostructure epitaxial design developed in the Phase I and II of the SBIR project. We will use commercially available manufacturing resources, scaling the technology from the small format 4x4 mini-array to a mid-format focal plane array (FPA) of 320x256 pixels integrated with an imaging readout integrated circuit (ROIC).

The proposed detectors will address: Free space, satellite-based optical communication with a high operating temperature, high speed photodetector. An imaging array for beaconless pointing as part of the Integrated RF and Optical Communication (iROC) development effort at NASA. High operating temperature, high sensitivity detector for quantum key distribution (QKD), as one example of quantum communications. Dynamic imaging array for short-wave lidar and atmospheric gas monitoring.

The proposed detectors will address: Enhanced lidar and imaging navigation. Reconfigurable and combined systems for navigation and optical communication. High operating temperature, high sensitivity detector for quantum key distribution (QKD), as one example of quantum communications. Form

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.
