Carrier transport in the separate-confinement heterostructure is taken into account. The modulation response is compared to experimental data and to predictions from calculations using only the free-carrier gain. The comparison shows that the inclusion of Coulomb enhancement in the theoretical calculations leads to better agreement between simulated and experimental data %Z Coulomb enhancement;modulation properties;quantum-well lasers;many-body effects;gain;modulation response;carrier transport;separate-confinement heterostructure;free-carrier gain;InGaAs-AlGaAs SQW laser;InGaAs-AlGaAs; %9 article
