Abstract

We present a method for fabricating 3D photonic crystal structures by means of interference pattern of laser beams. Four laser beams are introduced into a glass cell filled with a liquid photopolymerizable resin. The resin is polymerized according to the interference patter of four laser beams formed in the resin, so that a square lattice of solid polymer rod-array is formed. Four beams are introduced into the cell again from another face, which is perpendicular to the previous entrance face, to form another rod-array inside the previous one, thereby producing a 3D photonic crysatl structure. The shape of the formed lattice is so-called "wood-pile" which has diamond-like lattice symmetry. The lattice constant of the photonic crystal can be tuned by selecting incident angles of laser beams and can be minimized to about a half of the laser wavelength. After irradiation of laser light, the non-solidified resin is washed out of the polymer structure by ethanol. The proposed method does not require complicated multiple processes compared with the layer-by-layer fabrication method, and thick photonic crystals are immediately produced with high precision.
