Abstract : Semiconductor ring lasers are attractive, by the nature of their geometry, for short pulse generation through active mode-locking and colliding pulse mode-locking (CPM). However, to date, only CW operation of small diameter ring lasers in GaAs has been demonstrated. Recent advances in InP fabrication technology have enabled the realization of complex photonic integrated circuits using multiple quantum well (MQW) active regions and low-loss passive waveguides. Using these techniques, we have fabricated an 3.0-mm diameter InGaAsP MQW ring laser which is actively mode-locked at 9.0 GHz producing nearly transform limited 27 ps optical pulses.
