“…12 Very recently, these two optimized configurations with sizes matched for the obtention of an absolute PBG centered at 0.9 m have been processed in GaAs. 13 Preliminary measurements of reflectance spectra present an enhancement of the reflectance in good agreement with theoretical predictions. To design photonic devices, it is fundamental to know the thickness required to obtain fixed attenuation.…”

We present a study of the transmission coefficients of two-dimensional photonic band gap materials consisting of dielectric cylinders in graphite arrangement. By the study of the attenuation versus slab thickness, we determine the most efficient graphite configuration. We show how uncoupled modes create opaque regions for plane waves propagating along the Γ-P direction and widen the gap originating from the existence of forbidden photonic bands. Our results demonstrate that graphite structure is a promising geometry yielding an attenuation as strong as triangular structure with greater convenience in the fabrication at the submicronic scale.

“…Both of these structures present similar performances in obtaining PBGs in the infrared range. As the spatial period of a PC must be smaller than the wavelength of light to be controlled, these crystals have been fabricated in the near-infrared range, in GaAs (e ¼ 13.6) [10,11]. The situation is more difficult in the visible.…”

To optimize the appearance of photonic band gaps in nitrides, we study photonic crystals based on low dielectric constant materials. By calculating the photonic band structures we investigate the gap opening. In the case of microcavities, we have calculated the cavity modes by the plane wave method and a supercell approach. We have classified the modes using group theory. Our results demonstrate that gallery-like modes are more sensitive to a variation of the filling factor.

“…Photonic-crystal slabs are twodimensionally periodic dielectric structures of finite height that have a band gap for propagation in the plane and use index-confinement in the third dimension; they have been proposed as a more-easily fabricated alternative to true threedimensionally periodic photonic crystals. 2,[8][9][10][11][12][13][14][15][16][17][18][19] Although their structure and properties strongly resemble those of twodimensional crystals, slab systems require a fundamentally different, three-dimensional analysis. 10,16,19 We will demonstrate how such analyses apply to waveguides and explain the considerations that arise for line defects in photoniccrystal slabs.…”

Linear waveguides in photonic-crystal slabs

et al. 2000

Linear waveguides in photonic-crystal slabs, two-dimensionally periodic dielectric structures of finite height, are fundamentally different from waveguides in two-dimensional photonic crystals. The most important distinctions arise from the fact that photonic-crystal slab waveguides must be index-confined in the vertical direction ͑while a band gap confines them horizontally͒. We present a systematic analysis of different families of waveguides in photonic-crystal slabs, and illustrate the considerations that must be applied to achieve single-mode guided bands in these systems. In this way, the unusual features of photonic-crystal waveguides can be realized in three dimensions without the fabrication complexity required by photonic crystals with complete three-dimensional band gaps.
