Abstract

The refractive index is assumed to be a linear function of the dopant concentration. We investigate the core dopant evolution during the fused-fiber coupler fabrication by solving the convective diffusion equation. The tapering and the fusion of the coupler are considered as coupled phenomena. The slenderness of the geometry makes it possible to simplify the equations and to obtain a three-dimensional model for the velocity field. We present numerical solutions of the resulting equations and compare them with experimental measurements of the refractive index profile.
