Here, we extend high peak power picosecond pulse generation to high repetition rates by employing two monolithic tapered QD structures. The tapered mode-locked QD laser generates a pulse train at a repetition rate of 16 GHz with a pulse width of 1.15 ps at an average power of 6 mW. The active region of the novel tapered SOA structure consists of 15 InGaAs QD layers and the waveguide layout comprises two differently tapered sub-sections and a straight input section.
