Abstract: We demonstrate two high-speed electro-optic devices: an integrated lens/scanner and a variable radius collimating lens stack fabricated on a single crystal of Z-cut LiTaO$-3$/. The 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$+$MIN@1$/kV$+$MIN@1$/, a deflection angle of 12.68 mrad kV$+$MIN@1$/, and a scan rate of 225 kHz at 375 V were observed. The collimating lens stack is theoretically capable of collimating the output from 2 - 10 micron diameter channel waveguides. !15
