By coating patterned and aligned ZnO nanorod arrays with TiO2, a bottom–up process is used to fabricate a 2D photonic crystal (PC). The as-synthesized 2D PC slab shows a highly ordered air-hole array (see Figure) and exhibits a photonic bandgap that agrees reasonably well with the theoretically calculated value.
