Abstract
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 Δℏω∼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.Keywords
