We report on the generation of dual-wavelength self-mode-locking pulses from an InP-based quantum dot laser. The demonstrated device operates simultaneously at both 1543.7 and 1571.7 nm and has a repetition rate of 92.5 GHz. The pulse width is below 960 fs, and the average power coupled to a cleaved single-mode fiber is nearly 9 mW at a current bias of 60 mA.
