Abstract :
Strong >30-dB first-order Bragg-gratings were inscribed inside borosilicate glasses in a single laser waveguide-writing step driven by type-II photosensitivity response. Mode profiles, propagation losses, waveguide birefringence, and grating responses were optimized for the Telecom band.
