Dynamics and its Effects on Saturation Region in Semiconductor Optical Amplifiers
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2021 We focus on studying the dynamics of bulk semiconductor optical amplifiers and their effects on the saturation region for short pulse that differ, however there is the same unsaturated gain for both dynamics.
