Multiplexable Intrinsic Fabry-Perot Cavities using Femtosecond Laser Inscribed Scattering Centers

We propose a fabrication technique to multiplex Intrinsic Fabry-Perot Cavity sensors using femtosecond laser induced Rayleigh scattering centers. Up to 20 sensors were multiplexed and demodulated using a fast white-light interferometry demodulation algorithm.
