Abstract :
We propose and demonstrate an electrooptic Bragg deflection modulator using periodically poled MgO : LiNbO3 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.
