We introduce a technique to generate and read the digital signature of the networks,
channels, and optical devices that possess the fiber-optic pigtails to enhance physical layer …

We have shown the opportunity to use the unique inhomogeneities of the internal structure
of an optical fiber waveguide for remote authentication of users or an optic fiber line. Optical …

We demonstrate a novel silicon-photonic-based Physically Unclonable Function (PUF)
using grating-assisted contra-directional couplers integrated with perforated mi-croring …
