A monolithic two-section InGaSb/AlGaAsSb single quantum well mode-locked laser (MLL) emitting at 2 μm is demonstrated. The laser is able to lase in the continuous wave mode up to 80 °C, and passive mode locking operation with a fundamental repetition frequency of ∼18.4 GHz is observed up to 60 °C. T...
