Abstract

The waveguide Bragg gratings have been fabricated by the phase-mask method. An excimer laser with maximum 600mJ output pulse energy and uniform phase masks have been used. Hydrogen loading is often used for enhancing the uv photosensitivity of the core, however, the resultant gratings show significant aging effect. In the present study, high temperature thermal annealing process has been investigated to obtain thermal gratings and process parameters are deduced.
