Mode-locking of 1.3 μm InGaAs/GaAs quantum dot lasers was discussed. Hybrid mode-locking was also achieved. It was found that the minimum pulse width of the Fourier-limited pulses was 7 ps. Low uncorrelated timing jitter below 1 ps was also found. High-frequency operation of lasers was achieved by a ridge waveguide design. The study enables the introduction of 1.3 μm quantum dot lasers as high frequency optical comb generators.
