Paper Abstract

The major challenge in todays photonic crystal fabrication is the experimental realization of perfect, disorder-free structures. Macroporous silicon etching is a versatile technique for the manufacturing of large-scale well-ordered porous materials and three-dimensional photonic crystals. We investigate the degree of local disorder by scanning electron microscopy and a subsequent image processing, as well as the homogeneity of our large area crystals by an optical two-dimensional mapping. The observed disorder is related to the applied fabrication parameters. The deduced dependencies help to avoid disorder and to optimize our structures.
