New silicon photonics fingerprinting technique combats counterfeits

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a novel hardware fingerprinting technique for silicon photonics integrated circuits (PICs) to combat counterfeit and tampering threats. This method embeds unique two-dimensional photonic crystal patterns into PICs, which create distinctive optical signatures based on wavelength, polarization, and incident angle. The technique requires no additional fabrication steps beyond standard lithography and utilizes sub-50nm precision nanostructures, making forgery difficult and enabling cost-effective device authentication.
