Abstract

A simple but powerful method is proposed for the analysis of fibers whose refractive-index profile can be described in terms of a complex function, such as laser fibers. Existing methods for the analysis of fibers whose refractive-index profile can be described in terms of a real function are implemented alone in the analysis of complex refractive-index-profile fibers, resulting in extremely high accuracy for practical fibers.
