Erbium Doped Fiber Amplifier Performance using Different Host Materials in the Band 1450-1650 Nm: A Comparative Study

Abstract

A numerical investigation of the performance characteristics of erbium doped fiber amplifier using different host materials is presented. The emission and absorption curves of each of these hosts are fitted to Guassian fitting parameters. A software program is then implemented to calculate the gain coefficient, gain spectrum and the equivalent input noise factors in forward and reverse directions. The hosts under consideration are: almino-germanosilicate, bismuth, LiNbO3, tellurite, sodium niobium phosphate, oxyfluoride silicate, Al2O3 and fluoride phosphate glasses. The corresponding gain covers the 1450-1650 nm wavelength range.
