A multiexcitonic quantum dot in an optical microcavity

We theoretically study the coupled modes of a medium-size quantum dot, which may confine a maximum of 10 electron–hole pairs, and a single photonic mode of an optical microcavity. Ground-state and excitation energies, exciton–photon mixing in the wave functions and the emission of light from the microcavity are computed as functions of the pair–photon coupling strength, photon detuning, and polariton number.
