精细的一维光子晶体是由各种有机和生物聚合物，可以溶解或熔化，通过模板的溶液浇铸或注射成型材料在多孔硅或多孔二氧化硅多层（皱纹介质镜）结构。在通过化学溶解去除模板之后，聚合物铸件复制了母版的光子特征和纳米结构。我们证明，这些铸件可用作蒸汽传感器，可变形和可调的光学滤波器，并作为自我报告，生物可吸收材料。
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.
