Abstract

It is well-established that by applying ion-exchange technique, the gradient refractive index distribution is produced in a glass rod due to the diffusion of doped electro-polarizable ions. In this paper, the dopant concentration profiles were deduced by computer simulation under the various diffusion constants which depend differently on the dopant concentration. The refractive index distribution converted from the dopant concentration profile was compared with the index profile measured by differential interference microscope and the diffusion behavior of doped ions was investigated.
