Determination of optical fibre refractive index profiles by a near-field scanning technique
A simple and rapid method is described for determining the refractive index profile of an optical fiber by observation of the near-field intensity distribution. It is shown that in many cases the presence of tunnelling leaky modes is unavoidable and that these cause a length-dependent error in the m...
