Abstract

The negatively charged exciton (X^-) is observed to strongly couple with the microcavity (MC)-confined photons in a GaAs quantum well containing a two-dimensional electron gas with 0<n_e≤3×10¹⁰ cm^-2. This strong coupling results in the formation of charged polaritons. The coupling strength is found to depend on √n_e, in analogy to two-level atoms in a cavity. A model is suggested to explain this dependence. The analysis of the reflection and photoluminescence spectra shows that X^- is strongly admixed with the neutral exciton (X) via their coupling with the MC-photons. The linewidth dependence on n_e indicates that electron-polariton scattering is effective.
