Abstract [en]

Long wavelength monomode InGaAs/GaAs quantum dot (QD) distributed feedback (DFB) lasers with emission wavelength around 1325 ran are presented. Threshold currents below 19 mA for operating temperatures up to 70 degrees C and Output powers of 10 mW at 25 degrees C (6 mW at 70 degrees C) are observed. Error-free 10 Gbit/s transmission over 21 kin fibre with an extinction ratio of 8.5 dB at room temperature (5.1 dB at 70 degrees C) is demonstrated. The low threshold, low temperature sensitivity and high modulation speed were realised using complex coupled DFB lasers with ten stacks of self-organised MBE-grown QD layers and p-type modulation doping.
