Abstract
A method to measure the non-linear effective area in single-mode fibers is described. It is based on a Raman non-linear effect characterization set-up that uses a continuous-wave double beam arrangement in counter-propagating configuration. Non-linear effective areas are theoretically evaluated and experimentally determined for various types of fibers (standard single-mode fiber, dispersion-shifted fiber and large effective area dispersion-shifted fiber) and a correction factor that relates these effective areas with the mode field diameters of the fibers is introduced for taking into account the departures of the power distributions from the Gaussian shape.
