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 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.

... plot, shown in figure 3, is described below. First, consider the modes that are not confined to the glass, and extend into the air and out to infinity. Far away from the glass, these modes must closely resemble free-space √ plane waves ...
... plot Ln (k) for three different multilayer films. The left-hand plot is for a system in which all of the layers have the same dielectric constant; the medium is actually uniform in all three directions. The center plot is for a ...
... plot, which is for a nearly-homogeneous medium, looks like the homogeneous case with one important difference: there is a gap in frequency between the upper and lower branches of the lines. There is no allowed mode in the crystal that ...
... plot of figure 2. Suppose we try to approximate the second band near the gap by expanding w2 ( k ) in powers of k about the zone edge k = π / a . Because of time - reversal symmetry , the expansion cannot contain odd powers of k , so to ...
... plot L vs. ky , just as we did in figure 14. The yz plane is the plane of incidence, with the y direction parallel to the layers, and the z direction perpendicular to the layers. Now, however, we must consider both of the possible ...
