Abstract

Based on the major and difficult issues in the area of researching on photonic crystals, The partial differential equations of the monochrome electromagnetic wave transmitted in periodical dielectric medium and the theoretical basis for the laser holography to achieve photonic crystal templates are analyzed. With holographic grating theory, crystal lattice structure of the three-dimensional photonic crystals is designed. 632.8 nm red light crystal templates of the three-dimensional face-centered cubic photonic with double-beam three exposures methods are produced. The contrast ration, the rotation accuracy control and the index of refraction change influenceing the quality of photonic crystal templates end-product and how to solve are discussed. During the work process, double-beam three exposures methods are used to eliminate the modulation of recording beam polarized direction. At last, system of optical path and system performance during the work process of producing large area photonic crystal templates to eliminate the modulation of recording beam polarized direction are simplified and stabilized, seperately.
