Using 2-D and 3-D photonic crystals it is possible to control the propagation of light at arbitrary angles of incidence and not only the light normally incident as is the case for conventional optical films. Further, using photonic crystals, it is possible to achieve optical functionality not possible using conventional optical materials. This book provides a complete overview about photonic crystals including properties, applications, approaches and methods for the study. This book is structured into four main sections: 1. Introduction of Photonic Crystals. Many organisms have photonic crystals as part of their ‘bodies’. Recent research into the diversity of photonic crystals in nature has led us to question how such precise nanostructures form, with the hope that answers may lead to breakthroughs in their engineering. In a study of structural colors in nature, a remarkable convergence emerged in the nanoscale architecture of 2-D and 3-D periodic photonic crystals between species, families, phyla, and even kingdoms of organisms. Of the many types developed engineers, living organisms possess only four. These, however, occur in many unrelated species. It is possible that a combination of intra-cellular engineering and molecular self-assembly— as opposed to proportional genetic mutation—is the major factor in the evolution of photonic crystals in nature. In this section are reported examples of photonic crystals observed in nature and some examples of layouts such as gratings and guided waves. 2. Photonic crystals and applications. Applications such as optical logic devices, MEMS and bio-sensors are presented. Photonic crystals are promising technology in future optical signal processing and optical computing. In this direction optical logic gates are the fundamental components in optical digital information processing. In recent years, researchers have proposed other applications as photonic crystal MEMS based, and biosensors for bio-molecular detection systems (deoxyribonucleic acid (DNA) chips detectors). The listed topics are discussed in this section. 3. Photonic crystal fiber: Photonic-crystal fiber (PCF) confine slight in hollow cores or with confinement characteristics not possible in conventional optical fiber. PCF are used for applications in fiber-optic communications, fiber lasers, nonlinear devices, X Preface high-power transmission, highly sensitive gas sensors, and other areas. More specific categories of PCF include photonic-bandgap fiber (PCFs that confine light by band gap effects), holey fiber (PCFs using air holes in their cross-sections), hole-assisted fiber (PCFs guiding light by a conventional higher-index core modified by the presence of air holes), and Bragg fiber (photonic-bandgap fiber formed by concentric rings of multilayer film). This section shows some important applications of the PCF. 4. Design and Modeling: Photonic crystals are described exactly by Maxwell's Equation systems. Much of our research, however, is directed at achieving a higher level of understanding of these systems, so that it is possible to predict and explain their behaviour. This section discusses an overview about computational methods for photonic crystals including coupled mode and plane wave expansion theory.
