Elaborate one-dimensional photonic crystals are constructed from a variety of organic and biopolymers, which can be dissolved or melted, by templating the solution-cast or injection-molded materials in porous silicon or porous silicon dioxide multilayer (rugate dielectric mirror) structures. After the removal of the template by chemical dissolution, the polymer castings replicate the photonic features and the nanostructure of the master. We demonstrate that these castings can be used as vapor sensors, as deformable and tunable optical filters, and as self-reporting, bioresorbable materials.
精细的一维光子晶体由多种可溶解或熔化的有机和生物聚合物构建而成，通过在多孔硅或多孔二氧化硅多层（波纹介质镜）结构中对溶液浇铸或注塑材料进行模板化处理。通过化学溶解去除模板后，聚合物铸件复制了母版的光子特性和纳米结构。我们证明这些铸件可用作蒸汽传感器、可变形和可调谐光学滤波器以及自报告、可生物吸收的材料。
