Electrooptic Bragg Deflection Modulator Using Periodically Poled MgO : LiNbO$_{3}$

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