Effects of Angle of Incidence and Polarization in the Chiral Photonic Crystals

Oblique propagation of light through a planar layer of a chiral photonic crystal (CPC) is considered. The problem is solved using Ambartsumyan's layer-summation method. Specific features of the reflection (transmission) spectra in the presence of dielectric boundaries are studied. Apparent contradictions of the Belyakov-Dmitrienko theory with experiments are discussed. Possibility of the laser emission wavelength control in a CPC layer doped with a laser dye is analyzed. Characteristic features of the light absorption at oblique incidence are investigated.
