Reconstruction of Dielectric Constants of Multi-Layered Optical Fibers Using Propagation Constants Measurements
Journal article, 2016
We present a 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 epsilon for random noise level using these measurements.
