摘　　要：光子晶体概念自1987年的被提出以来,科学家们一直致力于在实验室用不同的手段合成不同材料和不同结构的光子晶体。利用正格子和倒格子理论对非共面三光束干涉的情况进行了系统而全面的分析,给出了晶格结构与入射光束配置之间的关系。研究表明,5种二维Bravais晶格都可以由非共面三光束干涉来形成,并进行了理论模拟。Since the concept of photonic crystals was first proposed in 1987, scientists have devoted themselves to the prepa- ration of photonic crystals with different materials and different topologies in various methods. In this article, systematical and comprehensive analysis to the interference of three noncoplanar beams was provided using both the direct and the reciprocal lattice theory. The relations between each lattice and corresponding recording geometry were quantitatively derived. It shows that all the five Bravais lattices can he formed by means of IFNB and verified by computer simulations.
