Paper Abstract

We report on our very recent demonstration of new waveguide Bragg gratings inscribed in a silver-containing oxide phosphate glass. We present the mask-less fabrication of first-order Bragg grating in the red/near-IR range. Based on coupled mode theory, these waveguide Bragg gratings show strong coupling constants, up to 3.9 mm-1 depending of the chosen Bragg grating geometry, which is relevant for applicative perspectives in integrated optics. Detailed description of these silver-sustained waveguide Bragg gratings will be provided, allowing for discussing both limitations and potentialities of the proposed innovative approach for the production of Bragg gratings in such photosensitive glasses.
