We have investigated the small-signal modulation characteristics of 1.1and 1.3-μm p-doped quantum-dot lasers in order to evaluate the potential of acceptor doping. The maximum measured 3-dB bandwidth of the 1.1- and 1.3-μm lasers are 11 and 8 GHz, respectively, which are only marginally higher than those in the corresponding undoped devices.
