Paper Abstract

Biological systems such as butterflies and beetles have developed highly elaborate photonic crystals to create their striking coloration. Especially, examples of the weevil and longhorn families (Curculionidae and Cerambycidae, respectively) possess a range of interesting three-dimensional photonic crystal structures operating at visible wavelengths, including non-close-packed lattices of cuticular spheres and diamond-based architectures. A low-temperature sol-gel bio-templating method was developed, to transform bio-polymeric photonic crystals into heat and photo-stable silica and titania inorganic structures. The fabricated oxide-based structures display good structural and optical properties.
