We investigate experimentally and numerically the gain recovery time and gain compression resulting from intraband effects induced by sub-picosecond optical pulses in bulk semiconductor optical amplifiers. With the help of data produced by pump-probe measurements, the dependence of the intraband gain dynamics on pulse energy, device bias current, and length is discussed. The simulation results show a good agreement with the experimental data.
