• Superposition of Nd3+/Yb3+ luminescence (Δλ = 100 nm) was obtained.
• We obtained ASE in 5-core fluorosilicate and fluorophosphate optical fibers.
• We analyzed Impact of the glass matrix and fiber length on the of ASE properties.
In the paper spectroscopic properties of two fluorosilicate and fluorophosphate glass systems co-doped with Nd3+/Yb3+ ions are investigated. As a result of optical excitation at the wavelength of 808 nm strong and wide emission in the 1 μm region corresponding to the superposition of optical transitions 4F3/2 → 4I11/2 (Nd3+) and 2F5/2 → 2F7/2 (Yb3+) can be observed. The optimization of Nd3+ → Yb3+ energy transfer in both glasses allows to manufacture multicore optical fibers with narrowing and red-shifting of amplified spontaneous emission (ASE) at 1.1 μm.
