Monolithic colliding pulse mode-locked (CPM) multiple quantum well lasers generating optical pulses as short as 600 femtoseconds are reported. The CPM laser is built on a single chip of InGaAs/InGaAsP multiple quantum well lasers. The pulse repetition rates are synchronized with an rf synthesizer up to 40 GHz in hybrid mode-locking. In passive mode-locking, a record high repetition rate of 350 GHz has been achieved. All the sub-picosecond pulses obtained have pulse shapes of sech 2 and transform-limited timebandwidth products between 0.30 to 0.34.
