Paper Abstract

3D photonic crystal structures can be fabricated into photopolymerizable resins by using laser beams interference with high precision. Three laser beams interfere into a glass cell filled with a liquid photopolymerizable resin to form a hexagonal periodic structure. Rods are formed in hexagonal arrangement after being photopolymerzed according to the 3D periodic light distribution which resulted from the lasers interference. Two beams of another laser interfere also to form layers which cross perpendicularly the rods array. After photo-fabrication, the non-solidified resin is removed by ethanol. The lattice constant can be selected by tuning the angles of the incident beams and the laser wavelength. We have fabricated a 500 m X 500 m X 500 m photonic crystal structure, the lattice constant of which is 1 m, and which contains 150 lateral layers.
