Abstract: In this paper, a comparison is made between the gain response of a quantum-dot semiconductor optical amplifier (QDSOA) under three different pumping schemes (optical, electrical, and electro-optical). We found that under equal pumping powers, the electric pump system is more efficient than optical and electro-optical ones. Simulation results show that the electrical pumping scheme not only provides a higher optical gain, compared to two other schemes, but also reduces QD-SOA gain recovery time. Moreover, the practical implementation of the electric pumping scheme is much simpler than two other ones
