Optical properties of Three-Dimensional Photonic Crystal with Face-Centered-Cubic Structure

摘要

Based on transfer matrix method (TMM), the model and calculation of 3-D Photonic Crystal with Face-Centered-Cubic (FCC) Structure are presented. The microsphere size, the crystal stack thickness and the incident angle have an influence on optical properties of 3-D Photonic Crystal. With the microsphere size increasing, the wavelength corresponding to the positions of PBG becomes larger causing structural color changing from blue to red. The reflectivity becomes higher and PBG is narrower when the crystal stack thickness increases. With the incident angle becoming larger, the reflectivity does not change significantly, while the wavelength corresponding to the positions of PBG becomes shorter causing structural color changing from red to blue.
