Zusammenfassung:We propose and demonstrate an electrooptic Bragg deflection modulator using periodically poled MgO :  \hbox{LiNbO}_{3} for the first time. It was found that annealing the device after the poling process was effective for reducing the relaxation phenomena. The maximum deflection efficiency as high as 97% was obtained for the violet-blue light. Also, the modulation of the UV light was accomplished.
