We study the counting statistics for electrons and photons being emitted from a driven two-level quantum dot. Our technique allows us to calculate their mutual correlations as well. We study different transport configurations by tuning the chemical potential of one of the leads to find that the electronic and photonic fluctuations can be externally manipulated by tuning the ac and transport parameters. We also propose special configurations where electron-photon correlation is maximal meaning that spontaneous emission of photons with a well-defined energy is regulated by single electron tunneling. Interesting features are also obtained for energy-dependent tunneling.
