Angle-resolved transmission spectroscopy of three-dimensional photonic crystals fabricated by direct laser writing

Oblique incidence optical transmission spectra of three-dimensional photonic crystal templates, i.e., woodpile structures, are presented. They are compared with transmission spectra calculated using a scattering-matrix approach. In addition, band-structure calculations are presented. The comparison reveals intricate details of the three-dimensional photonic band structure demonstrating the high overall sample quality. (c) 2005 American Institute of Physics.
