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 Z-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 Z axis of the first section and another electric field applied along the Y axis of the second section, light with an arbitrary elliptical polarization can be converted into a fixed linearly polarized state.
我们提出了一种通过周期性极化铌酸锂中的电光效应来控制光偏振的方法。使用了一个具有两个部分的Z切割铌酸锂单片集成芯片。第一部分不是周期性极化的，而第二部分是周期性极化的。通过在第一部分的Z轴方向施加一个电场，并在第二部分的Y轴方向施加另一个电场，可以将具有任意椭圆偏振的光转换为固定的线偏振状态。
