Abstract
We have written Bragg gratings of as much as 94% reflectance in german ium-doped optical fiber by two-beam interference of 244-nm continuous- wave UV light. We measured grating reflectance as a function of exposu re time for UV light intensities ranging from 1.5 to 47 W/cm2. The obs erved dependence of index modulation on time and intensity does not ag ree with the predictions of a model based on depletion of a defect pop ulation by one-photon absorption.
