“…Regarding PhC physics, the Kagomé structure is practically neglected [11], in spite of its large gapto-midgap ratio. On the other hand, the honeycomb or graphite lattice PhC has already been investigated [12][13][14][15] to some extent.…”

Possibilities of all-angle left-handed negative refraction in 2D honeycomb and Kagomé lattices made of dielectric rods in air are discussed for the refractive indices 3.1 and 3.6. In contrast to triangular lattice photonic crystals made of rods in air, both the honeycomb and Kagomé lattices show all-angle left-handed negative refraction in the case of the TM2 band for low normalized frequencies. Certain advantages of the honeycomb and Kagomé structures over the triangular lattice are emphasized. This specially concerns the honeycomb lattice with its circle-like equifrequency contours where the effective indices are close to -1 for a wide range of incident angles and frequencies.

“…A commonly used type of 2D photonic lattice is the hexagonal lattice, due to its almost circular Brillouin zone and corresponding large band gaps. [29][30][31] While the basic electrodynamic properties of photonic crystal structures have been investigated for some time and are well known, schemes for transition between an EBG structure and external microwave circuitry are still not very well developed. Although a number of experiments has been performed in the microwave frequency range, to our knowledge no special emphasis was laid on optimization of the coupling between photonic crystal waveguides and photonic crystal point defect modes.…”

We report on the controlled excitation of line and point defect modes in a two-dimensional hexagonal electromagnetic band-gap structure made of rods of dielectric material ͑aluminium oxide͒. We compared simulation performed with a numerical field simulation software and experimental measurements at microwave frequencies with regard to coupling from external waveguides to line defects and subsequent coupling to resonant modes. We observed that for a line defect in the photonic crystal the impedance matching to a waveguide is strongly dependent on the defect width. We furthermore demonstrated that the coupling to a localized defect resonance can be strongly influenced by the variation of certain single lattice elements, affecting transmission behavior and quality factor of the resonant modes.

“…As to lattice con"gurations, the most promising ones are thè honeycomba [21] (Fig. 2) and the`graphitea [22] structure where the widest band gaps occur when small regions of semiconductor are surrounded by large regions of air, i.e. when the semiconductor`area "ll-factora is low, a direct consequence of the high refractive index of the semiconductor.…”

During the last decade, photonic crystals, also known as photonic microstructures or photonic bandgap structures, have matured from an intellectual curiosity concerning electromagnetic waves to a "eld with real applications in both the microwave and optical regime. In this review, we shall focus on progress and the prospects for semiconductor structures that mainly involve guided modes interacting with periodic structures, but we also evaluate alternative material systems and fabrication methods, e.g. those based on self-organisation. We shall go from basic concepts, via a discussion of the state of the art, to device applications. Naturally, the discussion of the applications will be more speculative, but we attempt to evaluate the real prospects o!ered by photonic crystals at optical frequencies while considering practical limitations. In doing so, we identify a variety of areas such as the combination of quantum dot light emitters with photonic crystals that seem particularly promising. We discuss the prospects for enhanced light}matter interactions in photonic crystals and the related material and design issues. Overall, the aim of this review is to introduce the reader to the concepts of photonic crystals, describe the state of the art and attempt to answer the question of what uses these peculiar structures may have.
