圖書簡介This book systematically discusses the nonlinearities in the optics, optoelectronics and fiber communications. The theory of optical nonlinearity ties closely with the fiber communication technologies and the applied optoelectronics. This book discusses on the unified elaboration on fibers, semiconductor quantum wells and systems, and the next generation of high capacity lightwave information technologies with emphasis on the physical properties of the nonlinear refractive indices and optical absorption of the materials, as well as on the limitations and utilization of photonic nonlinearities for improving the systems and devices.
