Integrated tapered active modulators for high efficiency Gbps PPM laser transmitter PICs

Completed TRL 4 (started at 2, targeting 4)

Description

Modern satellites must be able to transfer large amounts of data at very high speeds. Free-space optical communication using laser sources offers the fastest possible bandwidth for these systems, making it an attractive solution for the future. The laser transmitter must be compact, lightweight, power efficient, reliable, and hardened against the harsh environment of space. Researchers at Rose-Hulman Institute of Technology and Freedom Photonics, LLC will develop a high-efficiency photonic integrated circuit (PIC) platform based on the highly reliable InGaAsP material system. The tapered active amplifier design under development is expected to enable Watt-class laser transmitter PICs capable of >100 Gbps data rates.

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.
