摘要：

The emission of light from a multiply excited atomic ensemble is examined and it is shown how symmetric (spin-wave) and nonsymmetric states of excitation radiate into spatially separate field modes. This observation has potential application to single-photon generation and spin-wave entanglement, since in the presence of atomic interactions it can result in isolated single-photon emission into a phase-matched field mode.
