The fourth edition of Nonlinear Fiber Optics discusses nonlinear phenomena that occur within optical fibers. Reflecting on developments in holey, microstructured and photonic crystal fibers, it includes new chapters on these fibers and on their effects and applications, which range from optical coherence tomography to high-precision frequency metrology. Taking into account recent research on polarization, additions have been made to chapters on stimulated Raman scattering and four-wave mixing. Targeted for optical engineers, researchers, scientists and graduate students, the 549-page volume addresses pulse propagation in fibers. Govind P.
