.Optical lattice transformation from 2D to 3D by holographic interference[J].Optoelectronics Letters,2009,5(6):434-436 Optical lattice transformation from 2D to 3D by holographic interference Abstract:       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). Hits: 3989 Download times: 327 View Full Text    Download reader
