We present polarization- and angle-resolved optical reflection of a fine artificial opal photonic crystal consisting of SiO2 spheres into a face-centered-cubic lattice. The measurement shows the polarization dependence on high-order reflection (energy region a/λ = 1.0 – 1.5). It is shown that the reflection peaks are strongly dependent on s- and p-polarized light illuminating on the sample. The experiment results are analyzed and compared with photonic bands which are obtained according to prediction based on group theory.
