    A top-cut hexagonal prism (TCHP) was designed with a height h=3.73 cm and a cross angle α=66° between side face and the base. By using the TCHP and holographic lithography, various photonic crystals (PhCs) were fabricated including symmetrical hexagonal structure, honeycomb structure and asymmetrical structures with elliptical rods in photo-resist film. Large area of electrically switchable PhCs were also obtained in polymer dispersed liquid crystal (PDLC) film. A good agreement is obtained for PhC structures between theoretical modeling and experimental results. Furthermore, far-field diffraction patterns and electrical switching characteristics were also investigated. The smallest droplets of liquid crystals is 10 nm. The switching voltage can be decreased to 13.3 V/μm.
