Paper Abstract
We report an all-fiber hydrogen sensing system for low-temperature operation. The sensor consists of a fiber Bragg
grating written in high-attenuation fiber and coated in Palladium. Heating the sensor with in-fiber light power greatly
enhances sensitivity at low temperatures. A multi-functional infrared light source is used to provide both in-fiber heating
and sensor monitoring. This technology promises a single fiber feedthrough solution for low temperature multipoint
hydrogen leak detection.
