Investigation of gain recovery for InAs/GaAs quantum dot semiconductor optical amplifiers by rate equation simulation
The gain recoveries in quantum dot semiconductor optical amplifiers (QD SOAs) are numerically studied by rate equation simulation. Similar to the optical pump-probe experiment, the injection of double 150 fs o...
