Function photonic crystals [PDF]
Physica E: Low-dimensional Systems and Nanostructures, 2011 In the paper, we present a new kind of function photonic crystals, which refractive index is a function of space position. Unlike conventional PCs, which structure grow from two materials, A and B, with different dielectric constants $ε_{A}$ and $ε_{B}$.

The diversity of three-dimensional photonic crystals
Nature Communications, 2021 Photonic crystals have a range of desirable properties for manipulating light. Here, the authors calculate and use the photonic band gap for thousands of such crystals to examine heuristics for their design and predict new photonic crystal structures.
