Paper Abstract

This paper presents the results of measurements of the time-dependent concentration of hydrogen in optical fiber during isothermal and isobaric hydrogen loading to increase its photosensitivity. A low-finesse fiber Bragg grating Fabry-Perot interferometer allows the determination of the evolution of the hydrogen concentration in situ. The estimated resolution of the measurements is better than 10 parts-per-million for a 10 millimetre long interferometer.
