Abstract:

Different kinds of optical lattice structures fabricated by holographic interference with top-cut prisms were simulated, which gave some references for making photonic crystal by prism method. Using holographic interference theory, optical lattices made by interference of several light beams with top-cut hexagonal prisms were analyzed, and the influence of light beams` number, polarization direction and phase to lattice structures was taken into account. Changing the number of light beams can fabricate normal and skew hexagonal optical lattice with different periods. Changing light beams` polarization characteristics can influence the shape of lattice points of optical lattice. Changing the initial phases of light beams can fabricate honeycomb structure. And tenfold rotationally symmetric optical quasi-lattice structures fabricated with top-cut pentagonal prism were simulated. Also the band-gap diagrams of hexagonal and honeycomb polymer photonic crystal were calculated by Plane Wave Expansion method, which demonstrated that honeycomb photonic crystal can form large photonic band-gap more easily.
