摘　　要：利用双光束干涉,在光敏材料上制作光子晶体结构.通过改变两束光之间的夹角可以改变制备样品的周期.改变曝光次数以及两次曝光时干涉条纹的夹角可以分别得到一维、二维正方晶格以及二维三角晶格结构的光子晶体.The fabricate photonic crystal on photosensitive material is proposed by double-beam interference.The period of the structure can be controlled by changing the angle between two beams.The one-dimensional grating structure and two-dimensional photonic crystals with square lattice and triangular lattice should be obtained by changing the time of exposure and the angle between the interference fringe of two exposures.
