Zusammenfassung:Rfgb manufacturing process and sensor that incorporates an rfgb obtained by said procedure. Disclosed is a method of manufacturing rfgb (1) from an optical fiber (11) and a sensor comprising an rfgb (1) obtained by said method. In particular, the present invention provides a method for obtaining rfgb from optical fibers that allows obtaining sensors with greater resistance to high temperatures. Generally, the method comprises the steps of: A) introduction of hydrogen to the optical fiber (11); B) inscription of a diffraction network in the optical fiber (11), preferably a bragg network (12); C) encapsulation of the optical fiber (11); And, once these steps are carried out, a regeneration heat treatment (200) is carried out to obtain an rfgb.

Se da a conocer un procedimiento de fabricación de RFGB (1) a partir de una fibra óptica (11) y un sensor que comprende una RFGB (1) obtenida mediante dicho procedimiento. En particular, la presente invención da a conocer un procedimiento para la obtención de RFGB a partir de fibras ópticas que permite obtener sensores con mayor resistencia a las altas temperaturas. De manera general, el procedimiento comprende las etapas de: a) introducción de hidrógeno a la fibra óptica (11); b) inscripción de una red de difracción en la fibra óptica (11), preferentemente una red de Bragg (12); c) encapsulamiento de la fibra óptica (11); y, una vez realizadas estas etapas se realiza un tratamiento térmico (200) de regeneración para obtener un RFGB.
