In recent years, photonics has found increasing applications in such areas as communications, signal processing, computing, sensing, display, printing, and energy transport. Now, Fundamentals of Photonics is the first self-contained introductory-level textbook to offer a thorough surveyof 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 light with matter, and the theory of semiconductor materials and their optical properties. Presented at increasing levels ofcomplexity, these sections serve as building blocks for the treatment of more advanced topics, such asFourier optics and holography, guidedwave and fiber optics, photon sources and detectors, electro-opticand acousto-optic devices, nonlinear optical devices, fiber-optic communications, and photonic switching and computing. Included are such vital topics as:* Generation of coherent lightby lasers, and incoherent lightby luminescence sources suchas light-emitting diodes* Transmission of light throughoptical components (lenses, apertures, and imagingsystems), waveguides, and fibers* Modulation, switching, and scanning of light through the use of electrically, acoustically, and opticallycontrolled devices * Amplification and frequency conversion of light by the use of wave interactions in nonlinear materialsDetection of light by means of semiconductor photodetectorsEach chapter contains summaries, highlighted equations, problem setsand exercises, and selected readinglists. Examples of real systems areincluded to emphasize the conceptsgoverning applications of currentinterest, and appendices summarizethe properties of one- andtwo-dimensional Fourier transforms, linear-systems theory, and modes oflinear systems.o appeal to r.
