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.
