Longitudinal coherence properties of the waves propagating through a birefringent fiber are investigated theoretically and experimentally. Significant loss due to the polarization-dispersion slope is observed clearly for the interference between the two orthogonally polarized HE11 modes. The results obtained experimentally reflect the theoretical predictions well for both the modulus of the degree of coherence and its curve shape versus the optical path difference in the wavelength region from 816 to 1540 nm.
