A monolithic two-section InGaAs/GaAs double quantum wells (DQWs) mode-locked laser (MLL) emitting at 1.06~\mu \text{m} is demonstrated. Stable mode locking operation is achieved up to 80 °C. The fundamental repetition rate is at 9.51 GHz with a signal-to-noise ratio (SNR) of more than 55 dB, and up...
