Electro-Optic Response of Nematic Liquid Crystals Aligned on Micro-grating Structures Fabricated by Direct Laser Writing

Abstract

We have previously presented a laser lithography method known as two photon excitation direct laser writing to fabricate micro-scale grating structures, and reported the dependence of the induced azimuthal anchoring energies on the height and periodicity of the grating. In this study, we report on how the anchoring strength affect the electro-optic response of nematic liquid crystals locally aligned on the micro-gratings.
