N2 - The dependence of multiple quantum well intersubband Rabi oscillations on the radiative coupling between different quantum wells is investigated. We show that in a highly doped multiple quantum well sample, radiative coupling has a large impact on coherent density oscillations, even stronger than the impact of many-body effects. Specifically, radiative coupling can dominate nonlinear optical response, such as Rabi oscillations of subband populations, yielding distinctively different excitation behaviors in the different wells of a multiple quantum well sample. The magnitude of radiative coupling may be controlled by varying the angle of incidence of the external electric field.
