Optical fiber hydrogen sensor using metasurfaces composed of palladium
文献摘要：
Palladium-based hydrogen sensors have been typically studied due to the dielectric function that changes with the hydro-gen concentration.However,the development of a reliable,integral,and widely applicable hydrogen sensor requires a sim-ple readout mechanism and an optimization of the fast detection of hydrogen.In this work,optical fiber hydrogen sensing platforms are developed using an optimized metasurface,which consists of a layer of palladium nanoantennas array sus-pended above a gold mirror layer.Since the optical properties of these palladium nanoantennas differ from the traditional palladium films,a high reflectance difference can be achieved when the sensor based on the metasurface is exposed to the hydrogen atmosphere.Finally,the optimized reflectance difference △R of～0.28 can be obtained when the sensor is exposed in the presence of hydrogen.It is demonstrated that this integrated system architecture with an optimized palla-dium-based metasurface and a simple optical fiber readout system provides a compact and light platform for hydrogen detection in various working environments.
