Photonic Crystals: Molding the Flow of Light - Second Edition
Princeton University Press, Oct 30, 2011 - Science - 304 pages
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.

We call this a leaky mode or resonance.7 The peak that the defect creates in the
crystal's density of states widens in proportion to γ; as the mode penetrates
farther into the continuum, farther and farther from the true bound state, the
We have expended a great deal of effort to understand the different ways in
which photonic crystals can reflect and trap light, thereby forming mirrors,
waveguides, and resonant cavities. These three components are themselves
very useful, ...

The light is transmitted for frequencies near the resonant frequency of the cavity,
and is reflected for somewhat lower or higher frequencies. The existence of the
resonance peak conforms with intuition: near the resonant frequency, light from ...
In temporal coupled-mode theory, the system is considered as a set of essential
components that are analyzed using only very general principles such as
conservation of energy. Our building blocks will be localized modes (resonant
