We investigate the formation of excitons bound by photons using a microscopic Hamiltonian involving quantum well electrons, holes, and microcavity photons. The negative reduced effective mass of the quantum well electron-hole (e-h) pair prevents Coulomb bound excitonic states, but the microcavity photon is capable of inducing binding. Using a theory based on Green’s functions we have calculated the spectral response of the quantum-well placed in the microcavity and compare it with recent experiment.
