Integration of electro-optic lenses and scanners on ferroelectric LiTaO{sub 3}

An integrated electro-optic lens/scanner device was fabricated on a ferroelectric LiTaO{sub 3} wafer. This was done using lithographically defined domain-inverted regions extending through the crystal thickness. A lens power of 0.233 cm{sup {minus}1}kV{sup {minus}1} and a scanner deflection of 12.68 mrad{sup {minus}1}kV{sup {minus}1} was observed. The authors also demonstrate an electro-optic lens stack collimator which collimates an input beam focused to a 5{micro}m waist diameter at {minus}2.3kV.
