Abstract
FDTD simulation was applied to study an optical field structure near the 2D photonic crystal surface. An effect of the optical field intensity redistribution was demonstrated for the first time. Spatial distribution of light intensity contains sharp peaks, focused in a certain parts of the crystal structure. The intensity peaks' magnitude could be very high. In case the incident light wavelength corresponds to the photonic crystal bandgap, the light could penetrate in a small depth into the crystal, but magnitude of the intensity peaks becomes several times higher in comparison to magnitude of the light intensity in the equal but homogeneous medium. Observed effect could be used for the enhancement of the light-matter interactions efficiency, for instance, for effective nonlinear conversion of light with photonic crystals, for Raman spectroscopy of small particles injected in crystals and etc.
