Study of high frequency response of self-organised stacked quantum dot lasers at room temperature

The high frequency response of self-organised stacked InAs/GaAs quantum dot lasers grown by MOCVD is investigated through relaxation oscillation measurements at room temperature. The highest relaxation oscillation frequency for a 265 µm cavity laser at room temperature is 5.3 GHz, corresponding to a 3 dB cutoff frequency of 8.2 GHz. Good static properties, such as high intemal quantum efficiency (91%) and low transparency current density (40 A/cm2) at room temperature are also obtained.
