The implementation of semiconductors to enhance optical signal was invented many years ago. The Semiconductor Optical Amplifiers (SOA) have much viability in different application areas. Nowadays, SOAs have been considered as one of the key solutions to for number functionalities in the evolution of electronic as well as communication systems. The requirement of moving towards the ultra-wideband systems and many other applications has enabled the usage of semiconductor optical amplifiers. This review paper focuses to describe some of the basic concepts behind the semiconductor optical amplifiers including the static and dynamic parameters characterizations. This survey paper also describes the various ranges of crucial applications of SOAs in several fields (such as: in packet switching, in UWB systems, in OCDMA systems etc.) https://pubs.sciepub.com/ajeee/12/1/2/ajeee-12-1-2.pdf SOA Static and dynamic parameters packet switching UWB OCDMA
