Abstract :
In this work we present a sensor based in a Bragg grating coated by a small amount of palladium. We explain the process of fabrication in detail, from the etching of the fiber to the deposition of the palladium. In this sensor the amount of hydrogen absorbed by the Pd is hydrogen concentration dependant and causes a stress that alters the transmission or reflection spectra of the FBG.
