Paper Abstract

Polarization anisotropy of the zero order forward-diffracted and the off-resonance transmitted light in the 3-dimensional thin film opal photonic crystals has been numerically computed and experimentally measured. Studies of the polarization anisotropy as a function of the incidence and azimuth angles of the incoming light have revealed strong anisotropy changes at diffraction resonances and in the ranges of the multiple-band diffraction. The opposite sign of the polarization anisotropy for different diffraction resonances has been observed. The cross-polarization coupling has been measured and identified as one of the reasons for changing the anisotropy sign. The correlation of the lattice ordering and the magnitude of the light polarization anisotropy has been demonstrated.
