NASA's Technology Transfer Program is seeking inquiries from companies interested in licensing a novel optical de-multiplexing method for quantum key distribution (QKD) encryption, developed by the NASA Marshall Space Flight Center. This technology utilizes a space-and-wave division method to efficiently separate low energy QKD photons from high energy optical signals, enabling secure encryption for free space optical communications. Interested parties can apply for licensing rights, which may be exclusive or nonexclusive, through NASA’s Automated Technology Licensing Application System (ATLAS) at the provided link. Please note that NASA does not provide funding for these licenses, and no follow-on procurement is anticipated from this notice; inquiries can be directed to NASA’s Technology Transfer Program via email.
