This paper presents a scheme to generate some Bell states of two orthogonal polarized modes in two separated cavities deterministically. The fidelity of the generated state is less than 1, which is mainly caused by fluctuations of interaction time between atoms and cavities, but the value of the fidelity is within our practical interest.
