Abstract.   A method is proposed for fabrication of fiber-optic phase sensor with the use of thermal annealing of fiber Bragg grating. Optimal conditions of the annealing for Bragg gratings with the required spectral properties are determined.
Keywords: fiber Bragg grating, thermal annealing, fiber-optic phase sensor, fiber-optic hydrophone
