Abstract

A new type of beam scanner is discussed based on a 1-D Fresnel zone plate consisting of titanium-diffused channel waveguides on LiNbO3. By electrooptically controlling the guided-wave phase, both beam scanning and 1-D focusing are achieved without a condensing lens. It was experimentally confirmed using the scanner with twenty-one Fresnel zones that the beam spot with a diameter of ∼50 μm at half-power level of diffraction pattern is scanned over a distance of ±70 μm in the focal plane with an applied voltage of ±40 V at 633 nm.
