Two-dimensional photonic crystals (PCs) are fabricated by using the wet chemical etching of high-resistivity silicon. The formation of the photonic band gap at a frequency of about 100 GHz is demonstrated by the measured and the 3D FDTD simulated transmittance of the transverse magnetic (TM) mode.
Transparent silicon solar cells can lead to increased energy conversion efficiency by enabling the collection and conversion of photons near and below the silicon band gap. This can be accomplished through the use of a low band gap solar cell in multiple junction systems. This analysis shows that the potential energy conversion efficiency gain for a one sun system is 7%. The design and fabrication...
Summary form only given. A simple cubic (SC) structure exhibiting a photonic band gap (PBG) was proposed by Sozuer and Haus (1993). Recently, Wada et al. (1997) reported a comparison between the FTIR transmission spectra of a pseudo-simple cubic lattice with theoretical transfer matrix results. The sample is composed of air rods with square and circular shaped rods made of silicon with the respective...
Summary form only given. Planar photonic crystal waveguides and devices may offer the possibility to build photonic circuits with greater density and new functionality compared to existing waveguide devices that are based on the control of light by refraction. The primary vehicles for this research are the study of microcavity lasers as a path to understanding new functionality, and the propagation...
Summary form only given. Introducing a line defect into a photonic crystal can create localized states within the photonic band gap of the crystal. Such a defect behaves as a waveguide, where the confinement of the light occurs via the photonic band gap (PBG) rather than total internal reflection. Aside from some recent optical experiments, most qualitative studies of photonic crystal waveguides have...
