Abstract- In this paper, InGaAs/GaAs Quantum Dot Semiconductor Optical Amplifier has been simulated. Rate equations have been obtained and by using propagation equation of optical pulse in SOA, its response has been investigated. Rate equations have been solved using 4th order Runge-Kutta method. The response of SOA to CW and Gaussian inputs has been investigated. Amplification of Gaussian pulse train has been investigated. It has been observed that increasing in the injection current increases the gain and gain recovery has been faster. Also, due to more amplification of forward edge of input pulse, asymmetry has been observed.
Keywords: Quantum dot semiconductor optical amplifier, Self-assembled InGaAs/GaAs QD, Simulation, Rate equations
