The semiconductor optical amplifier (SOA) has emerged as an  important component in many optical fiber communication, switching and  signal processing systems. Besides its basic use as an in-line  amplifier, SOAs have found use in a myriad of applications.  Semiconductor Optical Amplifiers provides a comprehensive  and detailed treatment of the design and applications of SOAs.  Key areas covered include:     *  Historical  background.      *  SOA principles - theory of amplification, gain,  noise, noise figure, polarisation dependence, spectral bandwidth,  dynamics.      *  SOA structures - travelling-wave, Fabry-Perot, DBR,  DFB, multi-section, twin-guide, polarisation insensitive  configurations, low-reflectivity coatings, angled facets, high-power  devices, gain clamped devices, SOA packaging.      *  Bulk and  quantum-well semiconductor materials.      *  Static and dynamic  modelling - travelling-wave equations, recombination mechanisms,  analytical approximations and computer modelling techniques. SOA  optimisation, slow and fast pulse amplification.      *  Applications  in optical communication systems - direct detection and coherent  receivers, amplified light detection statistics, preamplifier, in-line  amplifier, booster amplifier, amplifier chains, SOA based optical  network topologies, TDM, WDM, soliton transmission, system  experiments, analog systems.      *  Non-linear behaviour - cross-gain  modulation, self-phase and cross-phase modulation, four-wave mixing,  frequency chirping, bistability.      *  Functional applications -  intensity modulator, phase modulator, switch, add/drop multiplexer,  wavelength converter, in-line detector, dispersion compensator,  pulse-shaper, all-optical clock recovery, loop mirror configurations,  logic functions.      *  SOA photonic integrated circuits.      * Current developments and future prospects.   Semiconductor Optical Amplifiers is an invaluable information  source for researchers and engineers involved in SOA and optical  systems design and manufacturing. It is also useful to graduate  students, in optoelectronics, optical communications and optical  engineering, entering this rapidly growing and exciting field of  research and development.
