Abstract

In a simulation study, we show that correlated two-dimensional frequency-resolved fluorescence spectra of a quantum dot in a microcavity provide a sensitive probe for the distribution of multiexcitons. Polariton couplings lead to a fine structure of Rabi multiplets that allow us to resolve otherwise overlapping features of the different multiexcitons. These may be used to probe multiexciton generation.
