Statement of the Problem: For the past decades, erbium doped fiber amplifier (EDFA) has become a key element of modern telecommunication system due to Er3+ ion emission at 1.53 mm attributed to the 4 I13/2 → 4 I15/2 transition [1, 2]. The commercial EDFAs used in communication networks are made up of silica glass that has a relatively narrow bandwidth emission (~35 nm) resulting in a narrow gain curve, which limits its applications to meet broadband transmission. Among different host matrices, fluorophosphate (FP) glasses have received great interest for laser and optical amplifier applications because of their characteristic properties [3, 4]. Therefore, Er3+ -doped FP glasses can enlarge the emission cross-section and improve luminous efficiency because of the characteristic features of Er3+ ions and advantageous properties of mixed fluoride and phosphate glasses [5]. Hence, th.. View More»
