Description
Summary:•Superposition of Nd3+/Yb3+ luminescence (Δλ=100nm) 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 808nm strong and wide emission in the 1μm 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 1.1μm.
