High Resolution Liquid Crystal Phase Grating Formed by Fringing Fields From Interdigitated Electrodes
anisotropic phase gratings, nematic liquid-crystalline film, fringing, electric fields, interdigitated electrodes
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.
