Paper Abstract

A novel electro-optic beam deflector is reported based on ferroelectric domain inversion extending through the thickness of a Z-cut LiTaO3 wafer. The selective domain inversion is achieved by electric-field poling assisted by proton exchange, rather than proton exchange followed by rapid thermal annealing. The deflection sensitivity of the device was measured to be 5.0 mrad/KV. This is 93% of the theoretical value for this geometry, and a significant improvement over the value of 80% of theoretical previously reported for a waveguide deflector.
