Electrooptic diffraction modulation in Ti-diffused LiTaO(3)

The design and fabriction of electrooptic Bragg diffraction modulators in Ti-diffused LiTaO(3) waveguides are reported. The modulators developed have demonstrated 98% deflection efficiency for visible and near-ir operation with extinction ratios of at least 250:1 for both deflected (m = 1) and nondeflected (m = 0) beams.
