Optimizing four-wave mixing performance in semiconductor optical amplifiers

The Four Wave-Mixing (FWM) effect in a bulk Semiconductor Optical Amplifier (SOA) is widely used in all-optical communication networks for many applications such as wavelength conversion and fast optical switching. To best achieve such optical functions and bring them into practical stage, we present in this paper some performance criteria dealing with FWM phenomenon in both peaked and broad bandwidth gain SOA. The SOA with a large gain profile has given better performance by increasing the conversion efficiency and signal to background Ratio.
