Abstract

Based on a rigorous analysis of the Gaussian approximation applied to monomode optical fibers, a universal representation of the near- and far-field characteristics is given which covers all refractive-index profiles of practical interest. The accuracies of some methods of determining the most important parameters, e.g., the spot size w₀ and the cutoff wavelength λ_c, are compared, assuming the actual profile is unknown.
