Paper Abstract

A simple optical path for fabricating photonic crystals is presented. It is convenient to change the number of beams and its angles. Then photonic crystals of different lattices can be gotten. Recording material is home-made water-resisting photopolymer. The fabrication of photonic crystals with holography is simulated by matlab. By changing the number of beams and its angles, triangular, square and circular structures of photonic crystals are obtained. When polarization states of beams are changed, photonic crystals of different refractive index modulation are obtained. Via the simulation, the refractive index modulation of linearly polarized light is the highest. In the experiment, different exposures are set. And the best exposure is 20s, which is less than before. In this paper, photonic crystals using four light beams and five light beams are fabricated. Then, compare simulated results with experimental results and they are in substantial agreement.
