Query: Emission spectra and quantum efficiency of single-photon sources in the
  cavity-QED strong-coupling regime   We derive analytical formulas for the forward emission and side emission
spectra of cavity-modified single-photon sources, as well as the corresponding
normal-mode oscillations in the cavity quantum electrodynamics (QED)
strong-coupling regime. We investigate the effects of pure dephasing, treated
in the phase-diffusion model based on a Wiener-Levy process, on the emission
spectra and normal-mode oscillations. We also extend our previous calculation
of quantum efficiency to include the pure dephasing process. All results are
obtained in the Weisskopf-Wigner approximation for an impulse-excited emitter.
We find that the spectra are broadened, the depths of the normal-mode
oscillations are reduced and the quantum efficiency is decreased in the
presence of pure dephasing.
