Paper Abstract

We demonstrate a holographic approach for fabrication of large-area photonic crystal (PhC) microstructures by applying a single top-cut hexagonal prism. It is designed and used to fabricate various two-dimensional PhC structures in photo-resist films and polymer-dispersed liquid crystals (PDLCs) systems. Interference patterns from the beams from the top-cut hexagonal prism are calculated. SPM observations of the PhCs provide the basis for measurement of the structural parameters. A good agreement is obtained for the measured PhCs structural parameters and calculated results. Far-field diffraction patterns and electrical switching characteristics of the holographic PDLCs systems are also investigated.
