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.

Chapters 7 through 9 are all new, describing hybrid photoniccrystal structures
consisting, respectively, of 1Dperiodic dielectric waveguides, 2Dperiodic
photoniccrystal slabs, and photoniccrystal fibers. The final chapter, chapter 10 (

telecommunications is the optical fiber: a long filament of glass (or sometimes
plastic) that guides light, often for a distance of many kilometers. Optical fibers are

Then, for photonicbandgap fibers, we start with the case of twodimensional
periodicity and follow with onedimensional periodicity. The reason for this
reversal is not only that the holey bandgap fibers are closely related to their index

This results in radiation losses that increase exponentially with 1/Rb. Second, for
sufficiently large Rb, the bend radiation is negligible, and instead the losses in
highcontrast photoniccrystal fibers are dominated by coupling between guided
