Abstract
The authors demonstrate p-type modulation-doped strained-layer In0.35Ga0.65As/GaAs multiquantum well lasers which achieve a 3 dB direct modulation bandwidth of 20 GHz at a low CW drive current of 50 mA in a simple 3*200 mu m2 mesa structure. For the same device dimensions, a modulation bandwidth of 30 GHz was measured at a CW drive current of 114 mA. This is the highest direct modulation bandwidth reported for any semiconductor laser.
