We show for quantum dot (QD) semiconductor optical amplifiers (SOAs) operating in the regime where the gain is maximized, that gain saturation due to carrier depletion can be eliminated by increasing the SOA pump current density. At high pump currents, gain saturation in QD SOAs is then due to spect
