Development of A Novel Receiver for Coherent Communication

Optical communications through the atmosphere can be challenging due to the effects of atmospheric turbulence. To advance the technology readiness of this concept; we will procure and integrate a multi-channel integrated PIC receiver; develop the software codes; and perform a laboratory demonstration of real-time coherent combining in the laboratory environment. We will deliver hardware that can be directly integrated into a ground terminal to receive a space-to-ground communications link.

Reconstrucing a coherent signal post-detection using multiple phase measurements with a photonic lantern may enable vastly cheaper coherent detection than adaptive optics (AO) systems which require additional compensation for distortions in the optical wavefront.

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.
