Intentional birefringence induces an excess loss on one of the two polarization states of a single-mode optical fiber. Yet it may be not sufficient to avoid polarization coupling completely. In this case, we have some undesired effects, such as excess attenuation of the desired polarization as well, finite value of the extinction ratio, and residual polarization dispersion. Such effects are investigated through a coupled power model, which leads to completely analytical results.
