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.

If ω 1 =ω2, then we must have (H1 ,H2)=0 and we say H1 and H2 are orthogonal
modes. If two harmonic modes have equal frequencies ω1=ω2, then we say they
are degenerate and they are not necessarily orthogonal. For two modes to be ...
More careful considerations show that the lowestω electromagnetic eigenmode
H0 minimizes Uf. The nextlowestω eigenmode will minimize Uf within the
subspace of functions that are orthogonal to H0, In and so on. addition to

In this chapter, we will present several examples of threedimensional crystals
with complete band gaps: a diamond lattice of air holes, a drilled dielectric known
as Yablonovite, a woodpile stack of orthogonal dielectric columns, an inverse ...
Their polarizations are nearly orthogonal everywhere: the mode pictured at left is
mostly Ex, and the mode pictured at right is mostly Ey. The green circles show the
locations of the air holes. in figure 3. We call this the fundamental mode.
