We have investigated the mechanisms that give rise to the optical nonlinear response associated with excitons in 2D GaAs/GaAlAs Multiple Quantum-Well (MQW) structures. The analysis of the spectra has revealed in addition to the expected sources of excitonic optical non-linearity, temperature dependent propagation effects. These experiments bring to the fore the role of light propagation through a nonlinear medium.
