We report on electro-optic beam deflection using an annealed proton exchange waveguide in lithium niobate (LN) with microstructured serrated array electrodes. Due to the effect of LN material, experimental results show that and modulation can be realized relatively low voltages. The total length prism electrodes structure is ∼5 mm. With 20 V applied 50, 100, 150 μm wide waveguides, ∼1.28, ∼0.96, ∼0.64 deflections were obtained, respectively, which are accordance theoretical simulation. This configuration potentially optical scanning, high-speed switches, smoothing technology.
