The performance of an actively mode-locked coupled-stripe Al/sub x/'Ga/sub 1-x/'As-Al/sub x/Ga/sub 1-x/As quantum well laser in a tunable external cavity is described. Pulses as short as 50 ps are measured and a tuning range of ..delta..h..omega..approx.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.
