【Abstract】 The electromagnetic field equations in single-mode optical fibers under elastic deformation are formulated by a modified coupled-mode theory.The formulae of birefringence and polariza- tion dispersion of single-mode optical fibers with an elliptical core geometry are derived under bends and twists.The theore- tical results agree good with the experiments.更多还原
