| Research Abstract |
In this study, we proposed and developed a fiber optic sensor for safety hydrogan leakage detection. We employed a hetero-core fiber structure, which is mechanically rubust and can induce effectively light leakage. Palladium is known to be hydrogen absorption metal. Surface Plasmon resonance was utilized for the hetero-core fiber optic hydrogen sensor, which has high sensitivity to refractive index change with real-time responsibility. The hetero-core fiber optic hydrogen sensor has three thin metal layger around the hetero-core porition, which are Au, Ta2O5 and Pd, as a result, surface Plasmon resonance is enhanced. We simulated the proposed structure for surface Plasmon resonance, as a results, the proposed three metal layers hetero-core fiber sensor has surface Plasmon resonance curve and sensitivity to hydrogen concentration change. Additionally, we fabricatedd tha proposed hetero-core fiber hydrogen sensor, which can also be sensitive to hydrogen gas in real-time.
