We proposes an efficient scheme for deterministic generation of entangled coherent states (ECSs) of effective bosonic modes realized by collective excitations of two separate atomic ensembles in coupled cavities. Our protocol is fast compare to the convectional dispersive interaction induced operation in a cavity-assisted system. In addition, the implemented evolution is independent on the cavity field states with the assistance of strong classical fields, and thus not sensitive to the thermal states of the cavities. Our analysis shows that the protocol is robust against the main decoherence sources and unavoidable parameter variations. Moreover, current experimental design provides us the potential of extending this deterministic scheme to multimode case.
