Abstract

A rigorous analytical estimation is made of the propagation of power through a highly bent step-index parabolic cylindrical waveguide (PCW), the bending being across the direction of electromagnetic (EM) wave propagation. The scalar field approximation is employed for the analytical treatment. The general expression for power in the waveguide core is derived under the condition of vanishing refractive-index (RI) difference of the guide. The power patterns are shown for two different waveguide dimensions, and corresponding to different azimuthal modal indexes. The presented analysis is rigorous in the sense that no approximation is used to determine the representative functions for fields. It is found that an almost equal amount of power is carried by the bunched modes in thinner PCWs, and this feature affects guides having a higher thickness where the modes are less tightly bunched together.
