Paper Abstract

A novel holographic technique for fabricating three-dimensional photonic crystals (PhCs) by two-beam interference is presented in this paper. The optical setup in this method is much simpler and more flexible compared with other multi-beam interference methods, and large and uniform PhCs are easier to be obtained. In PhCs' fabrication, two coherent laser beams interfere and generate a set of two-dimensional interference fringes, which are recorded on a plate of photosensitive material. One laser beam is incident on the plate in normal direction and the other beam with an angle to the normal. Then with the laser beams maintained in a fixed relative position, the plate is rotated by 120 degrees about an axis through the center of the plate and a second recording is made. This procedure is repeated one more time, producing finally a superposition of three sets of interference fringes at angles of 120 degree to each other. After the chemical treatment, a three-dimensional PhC is fabricated in the material with a particular lattice structure that depends on the detail of the basic interference pattern. PhC with fcc lattice structure was fabricated in the experiment with the angle of 38.9 degrees between the two interference beams, verifying the effectiveness of the technique.
