摘要：

An overview is given about the recent improvement in 1.5 mu m QD lasers for direct modulation. Based on improved QD epitaxy with a reduced inhomogeneous size distribution, record values in small signal modulation bandwidth of more than 15 GHz and in digital modulation of up to 36 GBit/s were obtained. Due to the high modal gain and robust ground state transition, the temperature dependence of the laser performance could be very much improved with characteristic temperatures of T-0 = 125 K and T-1 near to 400 K. Also the impact of the temperature on the digital modulation speed will be discussed.
