We present empirical relations describing the spectral dependence of the spot sizes of the fundamental mode (along the major and minor axes) in a homogeneous elliptic core fiber. These relations are obtained by modeling the fundamental mode by a Gaussian distribution. Using these relations, we present a method for the determination of the equivalent step index (ESI) parameters of a monomode elliptic Core fiber. The applicability of the proposed method is shown through a) calculation of the cutoff wavelengths of a parabolic index elliptic core fiber and b) calculations of various fiber parameters like the core radii and index difference of an elliptic core fiber from recently reported experimental data.
