Abstract

Summary form only given. A multicomponent silicate photosensitive glass was used as a medium for Bragg grating recording. The Bragg grating formation is a two-step process: UV irradiation followed by thermal treatment. Samples were exposed to the interference pattern of a He-Cd laser at 325 nm with corresponding spatial frequency. The narrow band holographic mirrors were recorded for visible and IR regions. The total losses at 1550 nm were in the range of 1%. The high absolute diffraction efficiency of three-dimensional Bragg gratings recorded in PTR glass combined with the potential of narrow band filter fabrication pave the way for the creation of passive optical elements for DWDM technology such as add-drop elements or wave-lockers.
