A coupled-mode analysis is presented for a bent single-mode birefringent fiber. The coupling coefficients are given in closed forms. The effects of bending on the birefringence, the polarization dispersion, and the mode coupling in a bent birefringent fiber are discussed. Comparisons with other authors’ work are also made by reducing our results to the case of a bent, isotropic, single-mode fiber.
