This technology uses a novel quasi-crystal interferometer (QCI) made with standard single-mode silicon photonic components operating in the near infrared to achieve a robust, integrated silicon physical unclonable function (PUF). The PUF includes a unique integrated photonic form factor and single mode waveguides, rather than multimode waveguides, in primary aspects of the structure. Additionally, the use of a high sensitivity resonator and/or interferometer configuration enables near uniform optical confinement factors with the waveguide core. These features are achieved by using small modulations on a waveguide, rather than air holes or photonic crystals that would yield variable confinement factors. This optical PUF is the first to achieve true integration and demonstrate stability in a variety of environmental and thermal conditions.
• High sensitivity resonator and/or interferometer configuration, enabling near uniform optical confinement factors within the waveguide core
• Probes spatially distributes randomness in highly integrated fashion while providing inherent stability against probing and environmental/thermal conditions
• Feature extraction and correlation analysis achieve computationally efficient means for analyzing optical PUFs
