In this paper we investigated nonlinear properties and lasing in In x Ga 1-x As/GaAs multiple quantum wells grown by metal-organic chemical vapour deposition. A systematic study, performed by high excitation photoluminescence measurements as a function of excitation intensity, allowed us to identify
