We propose a method to control the polarization of light by the electro-optic effect in periodically poled lithium niobate. A single integrated chip of <i>Z</i>-cut lithium niobate having two sections is used. The first section is not periodically poled, whereas the second section is. With an electric field applied along the <i>Z</i> axis of the first section and another electric field applied along the <i>Y</i> axis of the second section, light with an arbitrary elliptical polarization can be converted into a fixed linearly polarized state.
