Abstract

We describe the properties of diffractive gratings induced in nematicliquid crystal thin films by fringing electrostatic fields induced by interdigitated ITO electrodes. The index of refraction variation produced by fringing fields gives rise to strong diffraction with resolution constrained only by the available lithography.
