文摘

A series of three-dimensional opal photonic crystals based on the polymer was synthesized and applied in the field of photo-induced birefringence. The data show that the photo-induced birefringence(PIB) of pure Sudan III film could be enhanced by increasing the thickness of azo films. When Sudan III was distributed on the three-dimensional opal photonic crystals, the photo-induced birefringence process could be modulated. In addition, the data also exhibit that the PIB processes with different pumping polarization directions are sensitive to the role of photonic crystals. The results could be beneficial to further understanding the photo-induced birefringence and utilizing the photonic crystals.
