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}, keywords = {carrier density;many-body problems;optical modulation;quantum well lasers;}, URL = {http://dx.doi.org/10.1109/3.658724}, author = { Tsou, B.P.C. and Pulfrey, D.L.} }
