An overview is given about recent results on static and dynamic properties of InP-based quantum dot lasers. High temperature stability in directly modulated lasers (T0 > 100 K, T1 > 500 K, up to 35 GBit/s) and narrow linewidth (< 150 kHz) with wide wavelength tuning range (C+ band) in an integrated QD DFB laser chip are obtained.
