In spring 2024, a research team from the LTCI laboratory at Télécom Paris, led by Télécom Paris, took up the challenge of free-space optical transmission security by demonstrating a chaos-based encryption method, and proved the applicability of this system over a distance of 30 metres in the far infrared.
The team demonstrated private optical communication in free space based on chaos synchronisation in one of the atmosphere's transparency windows. The chaotic light generated by a long-wave infrared quantum cascade laser is used to conceal the transmitted message, which is then decrypted using a double quantum cascade laser, thus guaranteeing greater confidentiality. This approach has an impact on the development of private transmissions in free space beyond conventional telecommunications networks.
Sara Zaminga, a doctoral student at Télécom Paris, and Frédéric Grillot present this chaos-based encryption method.
