AbstractWe have demonstrated a monolithic semiconductor passively mode-locked Bragg waveguide laser (PMBRL) based on a two quantum well active region. The lasers showed a threshold current of ∼33 mA at a saturable absorber reverse bias of 0 V in continuous wave operation (CW), with emission wavelength of ∼785 nm. A systematic study of a two section PMBRLs showed that these devices can generate pulse widths down to 211 fs at a 64 GHz repetition rate with a time-bandwidth product of 0.32. This range of pulse widths sets a new record for quantum well based devices.
