Systems and methods of producing unclonable devices are disclosed. Robust optical physical unclonable function devices use disordered photonic integrated circuits. Optical physical unclonable functions based on speckle patterns, chaos, or ‘strong’ disorder are so far notoriously sensitive to probing and/or environmental variations. A presently disclosed optical physical unclonable function is designed for robustness against fluctuations in optical angular/spatial alignment, polarization, and temperature using an integrated quasicrystal interferometer which sensitively probes disorder. All modes are engineered to exhibit approximately the same confinement factor in the predominant thermo-optic medium (e.g., silicon) and for constraining the transverse spatial-mode and polarization degrees of freedom. Silicon photonic quasicrystal interferometry is used for secure hardware applications.
A security device, comprising optical hardware having an integrated multiple scattering interferometer made with single-mode photonic components, forming an optical physical unclonable function device which has an unclonable device signature.
A method of producing unclonable devices for secure hardware and information security applications, including providing a robust optical physical unclonable function device using disordered photonic integrated circuits wherein the propagating and resonant modes contributing to the device's spectral signature exhibit approximately uniform confinement factors with the predominant thermo-optic medium.
