Abstract

Effect of soaking temperature on concentration of rare-earth ions in the optical fiber core during solution doping process was investigated. The dopant concentration of Er³⁺ and Ho³⁺ in the preforms and the fibers measured by the electron probe microanalysis and the optical spectrum analyzer was found to increase with decreasing the soaking temperature. The increase in the concentration of the Er³⁺ and the Ho³⁺ was attributed to the precipitation of the dopants due to the decrease in the solubility by decreasing the temperature.
