Abstract

A fiber optic sensor based on the wavelength division multiplexer coated with a palladium (Pd) thin film is designed for hydrogen gas detection. The sensing mechanism of this sensor is measuring the wavelength shift that is induced by the evanescent field interaction with the refractive index change of Pd film when it absorbs hydrogen.
