We present in this paper a wave coupling theory of linear electro-optic (EO) effect for quasi-phase matched (QPM) of focused Gaussian beam in an optical superlattice (OSL). The numerical results indicate that, due to the EO effect of an appropriate applied electric field, the output beam will form spatially inhomogeneous polarization, changing continuously in transverse section of beam; the confocal parameter has a significant impact on the output polarization of Gaussian beam and determines the half-wave voltage.
在本文中，我们提出了一种用于光学超晶格（OSL）中聚焦高斯光束准相位匹配（QPM）的线性电光（EO）效应的波耦合理论。数值结果表明，由于适当施加电场的电光效应，输出光束将形成空间不均匀的偏振，在光束横截面上连续变化；共焦参数对高斯光束的输出偏振有显著影响，并决定了半波电压。
