Light transport in a dilute photonic crystal is considered. The analytical expression for the transmission coefficient is derived. Straightening of light under certain conditions in a one-dimensional photonic crystal is predicted. Such behavior is caused by the formation of a localized state in transversal motion. The main contribution to the central diffracted wave transmission coefficient is due to states, that either close to the conductance band’s bottom or deeply localized in the forbidden…

Beam steering in planar-photonic crystals: from superprism to supercollimator
We utilize the anomalous dispersion of planar-photonic crystals (PhCs) near the dielectric band edge to control the wavelength-dependent propagation of light. Light beams with up to 20/spl deg/…
Self-collimating phenomena in photonic crystals
We found that self-determining collimated light is generated in a photonic crystal fabricated on silicon. The divergence of the collimated beam is insensitive to that of the incident beam and much…
Analysis of splitters for self-collimated beams in planar photonic crystals.
TLDR
Methods for beam splitting in a planar photonic crystal, where the light is self-guided as dictated by the selfcollimation phenomenon, are presented and the first one-to-three splitter in a self-guiding planar Photonic crystal is presented.
Capsize of polarization in dilute photonic crystals
TLDR
A theoretical model of dilute photonic crystal, based on Maxwell’s equations with a spatially dependent two dimensional inhomogeneous dielectric permittivity, shows that the polarization's rotation can be explained by an optical splitting parameter appearing naturally in Maxwell's equations for magnetic or electric fields components.

The term photonic crystals appears because of the analogy between electron waves in crystals and the light waves in artificial periodic dielectric structures. During the recent years the…

TLDR
Within the studied range of splitting structures, high output power was observed and verified experimentally and an arbitrary power ratio between the output beams can be achieved by varying the parameters of the splitting structure.

TLDR
Through quantitative studies of the beam evolution in a two-dimensional PhC, it is found thatsupercollimation possesses unexpected but inherent robustness with respect to short-scale disorder such as fabrication roughness, enabling supercollimation over 600 isotropic diffraction-lengths.
