Valence energy subbands and hole effective masses for quantum-well structures have been calculated, using GaInAs-InGaAsP and GaAs-AlGaAs material systems as an example. A Luttinger-Kohn 4 × 4 hamiltonian with heavy-hole and light-hole band mixing was used in the calculations. Systematic numerical re
Calculations of the femtosecond gain dynamics in InGaAs/AlGaAs strained-layer single-quantum-well diode lasers are presented and compared to experiments which use a novel multiple-wavelength pump probe technique. We develop a detailed theoretical model for the gain dynamics in a quantum well laser d
