Numerical analysis investigates gain properties in an optical fiber amplifier, indicating potential applications in telecommunications.
In this work, we numerically investigate the gain properties of an Yb3+:Er3+:Tm3+:Ho3+ co-doped optical fiber amplifier. The numerical simulations show that a gain higher than 15 dB in a wavelength range of 300 nm can be achieved. The erbium amplifies in the well-known C-band, while thulium and holmium amplify from 1760 nm to 2030 nm.
