Integrated electro-optic lens/scanner in a LiTaO3 single crystal.

We report what we believe to be the first stand-alone integrated electro-optic lens and scanner fabricated on a single crystal of Z-cut LiTaO3. The independently controlled lens and scanner components consist of lithographically defined domain-inverted regions extending through the thickness of the crystal. A lens power of 0.233 cm-1 kV-1 and a deflection angle of 12.68 mrad kV-1 were observed at the output of the device.
