Abstract
A permanent 248-nm photosensitivity response was locked into hydrogen-loaded standard telecommunication fiber by uniform 157-nm F/sub 2/-laser pre-exposure. Strong (>30 dB) fiber Bragg gratings were efficiently generated after hydrogen out-diffusion, improving the thermal stability. The 157-mn radiation produced weakly absorbing Si-OH and Ge-OH absorption bands at 1.39-/spl mu/m.Keywords
