A direct analysis of the dispersion equation in birefringent optical fibres
Abstract
Weakly-guiding, anisotropic step-index fibers are considered in the case where the permittivity tensor is everywhere diagonalized in the axes of the fiber. A method is shown which allows one to derive a mode and its dispersion equation with arbitrary accuracy in terms of the powers of the weak-guiding parameter. The method is applied to the derivation of the leakage loss of the y-polarized LP01 mode when epsilon-x is greater than epsilon-y.
