Controlling the spontaneous emission in the frame of cavity quantum electrodynamics (CQED), is of considerable interest because it suggests the possibility of optical devices such as a laser with an extremely low threshold due to the high coupling ratio of the emission into a lasing mode. On the other hand, controlling the spontaneous emission rate in the optical microcavities through cavity modes and thus enhancement of the single-photon blockade efficiency, is one of the key principles of realizing single-photon sources. In this proposal we want to control spontaneous emission spectrum of an open hybrid atom-cavity system consists of two two-level atoms driven. We analyze the effect of atom-atom coupling, atom-cavity interactions on the spectrum of spontaneous emission from the atoms in both transient and steady-state regimes. We investigate how the initial entanglement contained in the system affects spontaneous emission from atoms. We also explore the controlling role of driving laser field, atom velocity and quantum memory of leaky cavity on the spontaneous emission, and design a quantum control method to harness decoherence induced by the environment in both Markovian and non-Markovian regimes.
