Four wave mixing in semiconductor optical amplifier

Summary form only given. The semiconductor optical amplifier (SOA) has many potential applications in future all-optical transmission systems. Four wave mixing (FWM) in SOA has been proposed as a technique for performing wavelength conversion due to its high conversion efficiency and fast speed response in wavelength division multiplexing (WDM). A two-section SOA has been developed to increase its gain performance while facilitating the heat dissipation in the chip. The two sections are joined by a passive waveguide region. The amplifier wafer was grown by MOCVD (metal organic chemical vapor deposition) growth process on a [100] oriented InP substrate using two growth steps.
