An experimental and modelling investigation concerning the effects of p-doping on the DC and high-frequency properties of MBE grown In sub 0.35 Ga sub 0.65 As/GaAs strained-layer MQW lasers is presented. P-doping produces a substantial decrease in the non-linear gain coefficient, which can be attributed to a doping-induced decrease in the intraband relaxation time, and a small increase in the differential gain. The factors limiting the maximum measured modulation bandwidth of the p-doped devices (30 GHz) are analyzed and discussed.
