Provides a numerical reconstruction technique for dielectric profiles in optical fibers, but the results are preliminary and limited to numerical examples.
A method for reconstructing the refractive index profile of multi-layered optical fibers from propagation constant measurements is presented, achieving stable reconstruction under random noise.
We present new method for the numerical reconstruction of the variable refractive index of multi-layered circular weakly guiding dielectric waveguides using the measurements of the propagation constants of their eigenwaves. Our numerical examples show stable reconstruction of the dielectric permittivity function $\varepsilon$ for random noise level using these measurements.
