Abstract :
Analysis of hydrogen diffusion in glass fiber was performed using the finite element method. The wavelength shifts of long-period fiber gratings by hydrogen in-diffusion and out-diffusion were measured. The measured results were compared with the calculated wavelength shifts by the FEM analysis.
