## Abstract For InAsβGaAs based quantum dot lasers emitting at 1300 nm digital modulation with bit error rates below 10^β11^ at β2 dBm receiver power is demonstrated. Error rates of 10^β9^ or better are realized between 23 Β°C and 70 Β°C without current adjustment. Passive and hybrid modeβlocked QD l
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
