One short-cut transformation from one-dimensional (1D) to three-dimensional (3D) spatial optical lattices is simulated and studied. By adding mirror-symmetric beams for 3 original beams, the interference patterns from 2D to 3D can be obtained. Furthermore, by selecting appropriate polarization of the interference beams, the 3D structure can become 1D layered structure, and the period of the layers can reach the sub-wavelength. This result offers an alternative method to produce 1D and 3D photonic crystals, especially for the fabrication of optical band gap structures.
