Abstract

We report an experimental study of the response of a hydrogen sensor based on a palladium-coated tapered optical fiber, at different temperatures in the range [-30, 80]°C. The main features of the sensor's response have been correlated with the pressure-composition isotherms of the Pd-H system and its phase transitions. Moreover, heating of the palladium layer optically with an auxiliary laser diode, allows improving the sensor’s time response at low temperatures.
