Photonic Crystals: Molding the Flow of Light (Second Edition)Since it was first published in 1995, Photonic Crystals has remained the definitive text for both undergraduates and researchers on photonic band-gap materials and their use in controlling the propagation of light. This newly expanded and revised edition covers the latest developments in the field, providing the most up-to-date, concise, and comprehensive book available on these novel materials and their applications. Starting from Maxwell's equations and Fourier analysis, the authors develop the theoretical tools of photonics using principles of linear algebra and symmetry, emphasizing analogies with traditional solid-state physics and quantum theory. They then investigate the unique phenomena that take place within photonic crystals at defect sites and surfaces, from one to three dimensions. This new edition includes entirely new chapters describing important hybrid structures that use band gaps or periodicity only in some directions: periodic waveguides, photonic-crystal slabs, and photonic-crystal fibers. The authors demonstrate how the capabilities of photonic crystals to localize light can be put to work in devices such as filters and splitters. A new appendix provides an overview of computational methods for electromagnetism. Existing chapters have been considerably updated and expanded to include many new three-dimensional photonic crystals, an extensive tutorial on device design using temporal coupled-mode theory, discussions of diffraction and refraction at crystal interfaces, and more. Richly illustrated and accessibly written, Photonic Crystals is an indispensable resource for students and researchers.

... wavelengths, or “colors,” of light). We will also see that a photonic crystal can allow propagation in anomalous and useful ways. To develop this concept further, consider how metallic waveguides and cavities relate to photonic crystals ...
... wavelength, when incident on such a layered material, is completely reflected. The reason is that the light wave is partially reflected at each layer interface and, if the spacing is periodic, the multiple reflections of the incident ...
... wavelength of light). Let us now be a little more concrete. Consider a plane of glass of width a centered about the origin. We now wish to understand the band structure of the electromagnetic modes, by which we mean the frequency L ...
... wavelength of 2a, twice the crystal's spatial period (or lattice constant). There are two ways to center a mode of this type. We can position the nodes in each low-e layer, as in figure 3(a), or in each high-e layer, as in figure 3(b) ...
... wavelength (given by A = 27c/L). We are emphasizing general principles of periodic systems that will apply equally well to the more complicated two- and three-dimensional structures of the later chapters. It is worthwhile, however, to ...
