Since the publication of the first edition of Nonlinear Fiber Optics in 1989, the field of nonlinear fiber optics has virtually exploded. Revisiting the third edition to bring the book up to date so that it would remain a unique source of comprehensive coverage on the subject proved to be an ambitious undertaking. In order to do justice to this rapidly growing field, it became clear that the material required two separate books. The third edition of Nonlinear Fiber Optics deals with the fundamental aspects of nonlinear fiber optics, whereas this book, Applications of Nonlinear Fiber Optics, focuses on applications in the domain of lightwave technology. Topics covered include fiber gratings, fiber couplers, different types of interferometers, and fiber amplifiers and lasers. Particular attention is paid to optical applications related to compression of optical pulses and design of fiber optic communication systems.
