Abstract
In this paper a study of semiconductor optical amplifier (SOA) is presented. Construction and basic device characteristics are discussed in detail. The semiconductor optical amplifier is not limited to amplification purpose their functional applications are also important. Some functional applications of semiconductor optical amplifiers are also discussed. Further SOA based WDM networks and hybrid Raman/Semiconductor optical amplifier is also presented.
