Investigation on atmospheric turbulent free space optical transmission systems

This report presents the research and development works of Semiconductor optical amplifier used in free space optical communication systems. Matlab has been utilized in this study to simulate the semiconductor optical amplifier with various effects when free space optical signal is transmitted through it. SOA is a key component used in whole free space transmission system. It is used for scintillation suppression purpose. The SOA properties will directly affect the transmission quality and the distance. Different values of parameters and different modeling calculation methods will have different impact on the saturation gain. So when modeling the SOA, it is important to analyze the contribution of different parameters and calculation methods to the saturation gain.Bachelor of Engineerin
