Photonic Crystals: Molding the Flow of Light  Second EditionSince it was first published in 1995, Photonic Crystals has remained the definitive text for both undergraduates and researchers on photonic bandgap 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 uptodate, 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 solidstate 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, photoniccrystal slabs, and photoniccrystal 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 threedimensional photonic crystals, an extensive tutorial on device design using temporal coupledmode 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.

Left and middle panels correspond to the edges of the gap in the even guided
modes, while the right panel has odd symmetry with respect to the y=0 mirror
plane. The dielectric squares are shown as dashed green lines. (Recall that the ...
The guided band is shown as a red line, and extended modes of the crystal are
shown in shaded dark blue, with the band gap(s) shaded yellow. Left: TM mode

Eventually, one approaches the rayoptics limit, in which the guided modes are
described by a continuum of angles greater than the critical angle for total
internal reflection. However, as first pointed out by Birks et al. (1997), this need
not be ...
