具有强各向异性几何结构的三维周期微结构的制备对于包括光子晶体和双曲超材料在内的纳米光子器件具有重要意义。在本研究中，我们成功地建立了一种简单的方法，利用PMMA自组织胶体反蛋白石在100°C-115°C温度范围内拉伸定向拉伸变形，并利用反射光谱研究了具有各向异性几何结构的PMMA反蛋白石在不同程度上的光子带隙。光子带隙的波长与反蛋白石孔的长轴和短轴长度有关。光子带隙的波长变化受短轴长度变化的影响很大。当银和铂沉积在各向异性反蛋白石的上表面或共形涂覆在各向异性反蛋白石的内界面上时，也观察到了各向异性光学性质。各向异性比越高的结构，反射谷的波长随表面等离子体偏振度和截止频率随入射光偏振角的变化而变化越大。此外，共形包覆金属的PMMA反蛋白石在可见光或近红外波段表现出无限的介电性能。
The fabrication of three-dimensional periodic microstructures with strong anisotropic geometries is important for nanophotonic devices including photonic crystals and hyperbolic metamaterials. In this study, a simple method using self-organizing colloidal inverse opals of PMMA with directional tensile deformation by stretching was successfully constructed in the temperature range 100 °C–115 °C. Reflection spectroscopy was used for investigating the photonic bandgap of the PMMA inverse opal with anisotropic geometries in anisotropic different extents. The wavelengths of the photonic band gap were related to both the length of the pores in long-axis and short-axis of pores of the inverse opals. The wavelength changes of the photonic band gap significantly affected by the length variation in the short-axis. The anisotropic optical properties were also observed when Ag and Pt were deposited onto the top surface or conformally coated onto the interior interfaces of the anisotropic inverse opals. The structures with higher anisotropic ratios showed stronger variations in the wavelengths of the reflection valleys according to the surface plasmonic polarizations and cut-off frequencies with varying polarization angles of incident light. Moreover, the PMMA inverse opals conformally coated with metals presented indefinite dielectric properties in the visible or near-infrared wavelength region.
