Fabrication and characterization of high-speed integrated electro-optic lens and scanner devices

چکیده
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 LiTaO3. The lens and scanner components consist of lithographically defmed domain-inverted regions extending through the thickness of the crystal. A lens power of 0.233 cm'kV', a deflection angle of 12.68 mrad kV', and a scan rate of225 kHz at 375 V were observed. The collimating lens stack is theoretically capable ofcollimating the outpth from 2-10 micron diameter channel waveguides.
