Monolithic InP/GaInP quantum dot passively mode-locked lasers are realised for the first time, emitting in the 730 nm waveband. Devices with total cavity length between 2 mm and 3.5 mm, with uncoated cleaved facets, and saturable absorber (SA) sections representing approximately 20% of the total cavity length have been found to Q-switch, mode-lock or both, depending on operating regime. The influence of bias conditions on the characteristics of lasers with a 3 mm cavity length have been explored, resulting in generation of pulses at 734.7 nm with pulse repetition rates of 12.55 GHz and pulse durations down to ≈6 ps.
