Broadband wavelength tunability over 136?nm (between 1182.5?nm and 1319?nm) of picosecond pulses in passive mode-locked regime is demonstrated in a multi-section quantum-dot laser in external cavity configuration at room temperature. The maximum peak power of 870 mW with 15 ps pulse duration was achieved at 1226?nm wavelength.
