N2 - We demonstrate the mode-locked operation of a two-section quantum-dot laser in a broad temperature range. Stable mode-locking was observed at temperatures ranging from 20 °C to 70 °C, with signal-to-noise ratios well over 20 dB and a - 3-dB linewidth smaller than 80 kHz. In the temperature range between 70 °C and 80 °C, the mode-locking was less stable. It was found that in order to provide stable mode-locked operation with increasing temperature, the reverse bias on the absorber section must be reduced accordingly.
