  • Optical interferometric-based physically unclonable function device
    Patent number: 11889001
    Abstract: An apparatus for implementing a physically unclonable function via a network of interferometers implemented as a reconfigurable integrated optical circuit. The uncontrollable and non repeating fabrication variation in the manufacturing processes of integrated optics, combined with the sensitivity of interferometers creates inherently unique devices that can be used as reprogrammable physically unclonable function.
    Type: Grant
    Filed: March 19, 2019
    Date of Patent: January 30, 2024
    Assignee: United States of America as represented by the Secretary of the Air Force
