Abstract
An intrinsic optical fiber hydrogen sensor based on polarization-maintaining photonic crystal fiber (PM-PCF) Sagnac interferometer was proposed. The facing target sputtering technique with special Pd/Ag plate target structure was developed to deposit Pd/Ag composite film on PM-PCF. The characteristic of Pd/Ag film was measured and analyzed. An experimental setup for hydrogen sensing was built. The wavelength at different hydrogen concentration and the temperature interference were tested. The results showed the sensitivity was higher at low concentration range and good repeatability was obtained within measuring range of 4%. And the temperature affect was weak with special PM-PCF.
