Integrated Photonic Physical Unclonable Function using Highly Nonlinear Amorphous Silicon
We demonstrate the first integrated photonic physical unclonable function in CMOS compatible highly nonlinear hydrogenated amorphous silicon. We characterize the unclonability of our devices using spectrally-encoded optical pulses for challenge-response authentication.
