“…Currently, praseodymium-doped fiber amplifiers (PDFA), thulium-doped fiber amplifiers (TDFA), and neodymium-doped fiber amplifiers (NDFA) have been developed, but there is not yet a particular individual fiber amplifier that can cover the full optical communication window. Therefore, Bismuth-doped fiber amplifiers are also of great interest due to the ultra-broadband amplification properties of Bismuth ions [4][5][6][7]. Such Bismuth-doped glasses and fibers emitting in the ultra-broadband NIR at 1200-1600nm become very promising gain media for realizing ultra-broadband fiber amplifiers and lasers, and at the same time, they can make up for the shortcomings of conventional rare-earth ion-doped fiber lasers and amplifiers.…”

Broadband fiber amplifiers with materials doped with metal elements as optical media play an irreplaceable and important role in the current network hardware facilities. In this paper, based on the development of broadband fiber amplifiers and previous studies in the reference literature, this study has completed the modeling of gain spectrum of Bismuth-doped broadband fiber amplifier and its numerical simulation, mainly focusing on signal amplification in the 1200-1600nm band, and studied and simulated the relationship between gain spectrum of Bismuth-doped broadband fiber amplifier and fiber length, pumping power and ion doping concentration in this band. In the case of pumping light at a wavelength of 900nm, good gain results were obtained at the central wavelength of 1350nm. The bismuth-doped fiber performs well in terms of gain performance in the spectral range of 1200-1600 nm when the pump power is greater, the fiber length is around 3 m, and the doping concentration is approximately 0.61025. This is a brand-new, highly useful active medium for NIR lasers and fiber amplifiers.

Four non-zero-dispersion-shifted fibers with almost the same large effective area (A(eff)) and optimized dispersion properties are realized by novel index profile designing and modified vapor axial deposition and modified chemical vapor deposition processes. An A(eff) of greater than 71 μm(2) is obtained for the designed fibers. Three of the developed fibers with positive dispersion are improved by reducing the 1550 nm dispersion slope from 0.072 ps/nm(2)/km to 0.063 ps/nm(2)/km or 0.05 ps/nm(2)/km, increasing the 1550 nm dispersion from 4.972 ps/nm/km to 5.679 ps/nm/km or 7.776 ps/nm/km, and shifting the zero-dispersion wavelength from 1500 nm to 1450 nm. One of these fibers is in good agreement with G655D and G.656 fibers simultaneously, and another one with G655E and G.656 fibers; both fibers are beneficial to high-bit long-haul dense wavelength division multiplexing systems over S-, C-, and L-bands. The fourth developed fiber with negative dispersion is also improved by reducing the 1550 nm dispersion slope from 0.12 ps/nm(2)/km to 0.085 ps/nm(2)/km, increasing the 1550 nm dispersion from -4 ps/nm/km to -6.016 ps/nm/km, providing facilities for a submarine transmission system. Experimental measurements indicate that the developed fibers all have excellent optical transmission and good macrobending and splice performances.
