Abstract. Optical fibers are made of glass with different refractive indices in the (inner) core and the (outer) cladding regions. The difference in refractive index arises due to a rapid transition in the concentration of a dopant across the boundary between these two regions. Fibers are normally drawn from a heated glass preform, and the different dopant concentrations in the two regions will change due to dopant diffusion and convective transport induced by the flow. In this paper, we… CONTINUE READING
