1. Methodology for secure hardware and information security applications, comprising the steps of:
integrating a disordered photonic quasicrystal interferometer (QCI) with a single-mode filter into a silicon chip surface, for forming an optical physical unclonable function device which has an unclonable device signature, which optical physical unclonable function device is a robust device providing immunity against probing and against environmental variations; and
determining the identification of the optical physical unclonable function device based on its unclonable device signature,
wherein the QCI includes a waveguide structure having a non-repeating pattern along the length of the waveguide structure.
