TECHNOLOGY TRANSFER LICENSING OPPORTUNITY: Optical De-Multiplexing Method for QKD Encryption (LEW-TOPS-163)

NASAs Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: NASA inventors have developed a space-and-wave (SAW) division method to de-multiplex low energy quantum key distribution (QKD) photons from high energy free space optical transmissions. The method exploits available double-clad fiber optic cable with 9um core fiber diameter and 105um 1st cladding outer diameter. By optimizing wavelengths used for QKD photon and data transmission (wave division), a focusing lens can be used to cr
