We propose a protocol to generate a class of entangled states of N′Λ-type three-level atoms trapped in distant cavities by using interference of polarized photons. The proposed setup involves simple linear optical elements, cavities, and the conventional photon detectors that only distinguish the vacuum and the nonvacuum Fock number states.
