Paper Abstract

High concentration erbium-doped silica fibers were developed for amplification of L-band optical signals. Power conversion efficiency as a function of erbium-doping concentration for various erbium-doped silica fibers was analyzed and characterized at a wavelength of 1585 nm and at a pump wavelength of 1480 nm by using a two-stage amplifier and a C-band ASE filter. The experimental results are consistent with the simulation results. High Al doping and optimization of NA and erbium-doped region can help reduce the pair-induced quenching effects and improve the efficiency.
