1. A method of tapering a segment of an optical fiber from one having an initial radial profile into one having a desired radial profile, said method comprising the steps of:

  • softening the segment to form at least one softened portion, each said softened portion being located at a respective axial position;

    elongating said at least one softened portion axially, andsaid softening step and said elongating step being controlled in accordance with at least one parameter which is related to a normalized axial coordinate reference by which points of the initial radial profile map to corresponding points of the desired radial profile.
