The stretch-dependent extinction ratio for a birefringent single-mode fiber is examined. This ratio exhibits a quasi-periodic change as the fiber is axially stretched. This effect can be explained as the power transfer from a linearly polarized guided HE11, mode to an orthogonally polarized HE11 that is due to mode coupling.
