We have investigated the photonic modes at the surface of three-dimensional photonic crystals fabricated using a top-down approach involving two-step etching at angles of ± 45°. Numerical simulations revealed the properties of these surface modes, including their polarization characteristics and dependence on the surface structure. The formation of surface modes was experimentally demonstrated using an evanescent-coupling method and agreed well with the simulations.
