Abstract

At present, the wavelength range operated by optical fiber communication is 1530-1570nm, which can no longer meet the further needs of users for bandwidth. Therefore, it is necessary to develop a broadband optical fiber amplifier to improve the bandwidth and capacity of the optical fiber transmission system. This article proposes a composite structure of bismuth-doped fiber (BDF) and erbium-doped fiber (EDF). Genetic algorithm optimization is used to make the gain bandwidth larger and the gain spectrum flat. Parameters such as doping ion concentrations and fiber lengths of BDF and EDF are optimized to minimize the difference of amplification ratio between the bismuth-doped fiber and the erbium-doped fiber as much as possible. The results show that the amplifier can amplify the signal with a bandwidth of 1250-1650nm,greatly improving the wavelength range of optical fiber communication.
