Abstract

In this paper, we present the energy level, transition configuration, and numerical model of a bismuth-doped fiber amplifier for the first time, to the best of authorspsila knowledge. With a three-level system, the rate and power propagation equations of the model are solved to examine the effect of the fiber parameter and pump power on the bandwidth of the gain spectra. It can be predicted that when excited at wavelength in the 800-900 nm range, the amplifier can have a ultrabroad gain spectra in the 1.2-1.62 mum range, which cover the low-loss windows of the all-wave fiber.
