Abstract

A special type of annular elliptical fiber with a conducting helical winding on one of the core-cladding interfaces is proposed and investigated theoretically. Using the elliptical coordinate system, boundary conditions are derived, and field components for the even and odd modes are obtained. The eigenvalue equations for the proposed elliptical waveguide are determined by solving an eight-order determinant equation, which involves Mathieu functions, modified Mathieu functions, and their derivatives.
