Abstract :
We report the first demonstration of a bulk optical Bragg deflector based on an electro-optically induced grating in z-cut periodically poled LiNbO/sub 3/ (PPLN) operating at a wavelength of at 1.064 /spl mu/m. Discussions on the reduction of photorefractive damage by control of the grating period are presented.
