Abstract

Summary form only given. H2-loading is an established technique to photosensitise fibres for fabricating short-period (fibre Bragg gratings FBGs) and long-period gratings (LPGs). However, the H2-diffusion effect on the spectral response is far more significant in LPGs than in FBGs (reported previously). For a systematical investigation we have assessed this effect in LPGs for H 2 in- and out-diffusion at high- and low-pressures with long and short photosensitising time lengths.
