Functional photonic crystals are artificial structures whose spatial periodicity of dielectric constant is of the same length scale as the wavelength of light to be manipulated. One of the main problems in constructing a three-dimensional photonic crystal is the complexity of its preparation. Methods used to date have involved several steps of lithographic and microelectronic processing. Kennedy et al. present results using a glancing angle deposition (GLAD) technique in which a large array of square lattice spirals can be prepared in a one-step process. Theoretical analysis predicts favorable photonic properties for this structure.—ISO
