Abstract

Recently, we presented a simple 3D model based on a combination of disordered Bragg stacks capable to entirely mimic the optical properties of the scales of the white beetle Cyphochilus. Due to its simplicity, we use this model here to investigate numerically the influences of filling fraction and anisotropy on the scattering properties, which are under ongoing debate. Moreover, we present an experimental realization of our model and the first measurement of the entire photon lifetime distribution within the scales and our model as well. Appropriate simulations reveal strategies to design strongly scattering structures with tailored photon lifetime distributions.
