1. A method of tapering a segment of an optical fiber from one having an initial radial profile extending axially over an initial domain into one having a desired radial profile extending axially over a final domain, 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 determined based on a normalized axial coordinate reference by which points of the initial radial profile map to corresponding points of the desired radial profile, said normalized axial coordinate reference being an axial coordinate reference according to which the initial domain and the final domain are equal to one another.
