Design and synthesis of laser inscribed flexible Bragg gratings containing silicon oxynitride-doped silicon thin film for authentication applications with the insights from X-Ray Absorption Spectroscopy and Quantum Mechanical Calculations

Silicon-on-insulator is mostly the main driving material system for the field of silicon photonics, including PICs, due to high index contrast and compatibility with current semiconductor manufacturing processes [1]. A recent example is silicon oxynitride-doped silicon [2] discovered recently by our
