Query: Light-matter interaction in doped microcavities   We discuss theoretically the light-matter coupling in a microcavity
containing a quantum well with a two-dimensional electron gas. The high density
limit where the bound exciton states are absent is considered. The matrix
element of interband optical absorbtion demonstrates the Mahan singularity due
to strong Coulomb effect between the electrons and a photocreated hole. We
extend the non-local dielectric response theory to calculate the quantum well
reflection and transmission coefficients, as well as the microcavity
transmission spectra. The new eigenmodes of the system are discussed. Their
implications for the steady state and time resolved spectroscopy experiments
are analyzed.
