This book provides a comprehensive review of the state-of-the art of optical signal processing technologies and devices. It presents breakthrough solutions for enabling a pervasive use of optics in data communication and signal storage applications. It presents presents optical signal processing as solution to overcome the capacity crunch in communication networks. The book content ranges from the development of innovative materials and devices, such as graphene and slow light structures, to the use of nonlinear optics for secure quantum information processing and overcoming the classical Shannon limit on channel capacity and microwave signal processing. Although it holds the promise for a substantial speed improvement, today's communication infrastructure optics remains largely confined to the signal transport layer, as it lags behind electronics as far as signal processing is concerned. This situation will change in the near future as the tremendous growth of data traffic requires energy efficient and fully transparent all-optical networks. The book is written by leaders in the field.

Nonlinear optical studies of periodic dielectric structures have blossomed in the past two decades. New fabrication techniques are producing fiber grating and multidimensional photonic crystals in materials where the refractive index can be varied by light pulses and beams. Gap solitons that can propagate at any velocity from zero to the speed of light and spatial solitons that prevent the diffractive spread of light in waveguide arrays are two examples of the new phenomena described in this book. Microstructured optical fibers allow control of the guided mode dispersion for broadband light generation and new soliton phenomena. Many new materials and structures are being developed that will impact new optical devices with applications in optical communications and optical data processing. All the above topics are addressed in detail in this book.

Brillouin Scattering, Volume 109 in the Semiconductors and Semimetal series, marks the centenary of Leon Brillouin's seminal 1922 paper which provided a detailed theory of the effect that now bears his name. Stimulated Brillouin Scattering (SBS) is the strongest third order optical nonlinearity and plays an important role in contemporary science and applications, particularly lasers, communications, and fibre optics, as well as playing a new role in experimental physics and the life sciences. This volume provides a foundational perspective on Brillouin scattering, starting with a historical review of Brillouin scattering, the theory of SBS and the convergence between SBS and Optomechanics. We then consider SBS in several different waveguide geometries, including photonic crystal fibres, integrated optics and superfluids.

Brillouin Scattering, Part Two, Volume 110 in the Semiconductors and Semimetal series, marks the centenary of Leon Brillouin's seminal 1922 paper which provided a detailed theory on the effect that now bears his name. Sections in this new release include Optical Fiber Sensors Based on Stimulated Brillouin scattering, Brillouin-based RF frequency sources, SBS for Microwave Photonics (MWP), Engineerable Brillouin processes for integrated photonics, SBS in optical communication systems - the good, the bad and the ugly, Slow light, dynamic gratings and light storage, Non-reciprocity in Brillouin scattering, Electromechanical Brillouin Scattering, and Brillouin light scattering for studying mechanics of biological systems. Stimulated Brillouin Scattering (SBS) is the strongest third order nonlinearity and plays an important role in contemporary science and applications, particularly lasers, communications, fiber optics and basic physics. This volume provides different perspectives on current technological contexts of SBS in a range of different application areas, including sensing, communications, radar, imaging and information storage.
