Paper Abstract

Mode splitting of higher order modes in elliptical dielectric waveguides has been addressed theoretically in great detail since the 1960s. This work presents for the first time detailed experimental measurements of mode splitting in elliptical core optical silica fibers, with a semiminor to semimajor ratio ranging from 1.0 to 0.1. The experimental data are compared with numerical simulations obtained from finite element calculations performed on fiber 2-D refractive index profiles from each of the studied fiber pieces.
