本文报道了利用透明叉指电极产生的横向（边缘）电场在液晶薄膜中形成各向异性相位光栅。这些光栅产生高衍射效率（>30%），具有对读出光束入射角的强依赖性。此外，观察到的缺陷壁的形成，具有显着的相位光栅的衍射特性的影响。
We report the formation of thin anisotropic phase gratings in a nematic liquid-crystalline film by use of lateral (fringing) electric fields induced by transparent interdigitated electrodes. These gratings yield high diffraction efficiency (>30%) with a strong dependence on the readout beam incidence angle. In addition, the formation of a defect wall is observed that has a significant effect on the diffraction properties of the phase grating.
