Paper Abstract

Antimony-germanate glasses co-doped with Er 3+ /Tm 3+ ions as a material for active waveguides application have been investigated. In result of optimizations of rare earths, concentration wide (Δλ FWHM =420  nm ) luminescence emission in the range of 1.4 to 1.9 μm was obtained for molar composition of 1%Er 2 O 3 : 0.25%Tm 2 O 3 . The influence of the molar ratio of active ions on the luminescence spectra has been investigated. Luminescent properties of fabricated glass indicate that elaborated glass is promising material for broad tunable integrated laser sources and broadband optical amplifiers.
