文摘The optical lattice transformation from 2 dimensions(2D) to 3 dimensions(3D) by holographic interference is studied.The 2D optical lattices can be formed by 3 noncoplanar beams,and in this paper by adding another three beams,a 3D interference lattice structure is obtained.The added beams and the original ones are mirror symmetry(by using a reflective mirror).The simulation results show that the lattices become ellipsoids from 2D columns,which are periodic in the z direction.The calculations and numerical simulations provide a useful theoretical guide for fabricating 3D photonic crystals(PCs).
