The dynamics of a dissipative coupled system consisting of N two-level atoms and their resonant photon mode, each of which is coupled to its reservoir, is studied for the case of only one atomic excitation involved. A similarity between an elementary excitation in the system and a polariton in a dielectric crystal is pointed out. A relationship between the photon emission to be observed and the resonance trapping of photon is clarified. The time behavior of radiation intensity has either a damped oscillatory or an overdamped feature, depending on the strength that the photon emitted from the excited atom reacts on the atomic system.
