Contemporary, attention is paid to photonic crystals, which can strongly modify light propagation through them and enable a controllable light manipulation.

The contribution is focused on a sub-wavelength 2D structure formed by Al₂O₃ layer on silicon substrate, patterned with periodic hexagonal lattice of deep air holes. Using various laser sources of light at single wavelength, azimuthal angle dependence of the mirror-like reflected light intensity was recorded photo-electrically.

The results obtained can be used to sample the band-structure of leaky modes of the photonic crystal more reliably and help us to map the photonic dispersion diagram.
