Paper Abstract

Transmission spectra of thin opal films prepared by crystallisation in moving meniscus have been obtained in orthogonal polarisations in the wavelength range including the low and the high order photonic bandgaps. The anisotropy of light propagation in opal films has been studied as a function of the angle of light incidence, orientation of the opal lattice with respect to the light incidence plane, wavelength and polarisation of light. Clear correspondence between the spatial and the polarization anisotropy of light propagation has been demonstrated. The deviations of the opal film transmission from the commonly used model have been discussed.
