Abstract

Experimental results are reported on the modification of the group velocity in the Ti-diffused LiNbO/sub 3/ waveguides with dual Bragg gratings. The Bragg gratings were fabricated along the Ti-diffused waveguides. The average bandwidth was measured to be approximately 30 GHz separated by 30 GHz. Calculation showed approximately 10% modification of the group velocity between the stop bands.
