The interaction of two-level atoms with two modes of a resonator, formed by two weakly coupled cavities, is investigated. The first atom, passing through one of the two cavities, excites the two field modes. The second atom then, passing through the other cavity, tests the excitation. Since the photon generated by the first atom may be in the first or the second cavity, quantum interference phenomena are observed. Furthermore, the setup can be used to generate maximum entangled pairs of atoms.
