Bicontinuous Cubic Block Copolymer Photonic Crystals

Authors


Abstract

Three-dimensional photonic crystals are fabricated from block copolymers, forming a double gyroid network structure. Further processing produces three-dimensionally nanoporous, freestanding materials (see Figure), and allows dielectric enhancement and infiltration, which dramatically improve optical and material properties. These etched materials provide a path to highly effective photonic crystals via self-assembly.
