The performance of an actively mode-locked coupled-stripe Alx’Ga1-x’As-AlxGa1-xAs quantum well laser in a tunable external cavity is described. Pulses as short as 50 ps are measured and a tuning range of Δhω∼37 meV>kT, which is not the limit, is demonstrated. The existence of the transverse modes of coupled-stripe lasers increases significantly the spectral density of available lasing modes (for mode locking) compared with a single-stripe laser.
