Fundamentals of Photonics
Now in a new full-color edition, Fundamentals of Photonics, Second Edition is a self-contained and up-to-date introductory-level textbook that thoroughly surveys this rapidly expanding area of engineering and applied physics. Featuring a logical blend of theory and applications, coverage includes detailed accounts of the primary theories of light, including ray optics, wave optics, electromagnetic optics, and photon optics, as well as the interaction of photons and atoms, and semiconductor optics. Presented at increasing levels of complexity, preliminary sections build toward more advanced topics,
such as Fourier optics and holography, guided-wave and fiber optics, semiconductor sources and detectors, electro-optic and acousto-optic devices, nonlinear optical devices, optical interconnects and switches, and optical fiber communications.
Each of the twenty-two chapters of the first edition has been thoroughly updated. The Second Edition also features entirely new chapters on photonic-crystal optics (including multilayer and periodic media, waveguides, holey fibers, and resonators) and ultrafast optics (including femtosecond optical pulses, ultrafast nonlinear optics, and optical solitons). The chapters on optical interconnects and switches and optical fiber communications have been completely rewritten to accommodate current technology.
Each chapter contains summaries, highlighted equations, exercises, problems, and selected reading lists. Examples of real systems are included to emphasize the concepts governing applications of current interest.

5.2 ELECTROMAGNETIC WAVES IN DIELECTRIC MEDIA The character of the
medium is embodied in the relation between the polarization and magnetization
densities, 7 and M, on the one hand, and the electric and magnetic fields, £ and ...
is the lj — K dispersion relation. Here, g — 2n/A is the fundamental spatial
frequency of the periodic medium. The function cos(2nK/g) is a periodic function
of K of period g = 2n/A, so that for a given u>, (7.2-17) has multiple solutions.
C. Dispersion Relation and Group Velocities The tion dispersion relation (u>
versus 0) is obtained by writing the self-consistency equa- (8.2-2) in terms of 0
and u. Since A;2 = (w/ci)2 - 02, (8.2-2) gives 2flf*/^4 -/?2 = 2v?r + 27rm. (8.2-19)
