Rare-earth doped materials for optical waveguides

In the paper the analysis of luminescence emission in the VIS spectra range of fabricated multicomponent glasses doped with rare-earth ions and PMMA doped with dyes were presented. Up-conversion emission in: germanate glass co-doped with 0.5Yb₂O₃/0.75Eu₂O₃ mol% under 976 nm excitation has been investigated. Down-conversion mechanism was analyzed in phosphate glasses doped with 0.5 mol% Tb₂O₃ and PMMA co-doped with fluorescein and rhodamine B. Phosphosilicate glasses doped with Er³⁺ ions have been also studied in order to fabricate target for manufacturing planar waveguides by RF-sputtering deposition. Fabricated materials can be used for fabrication of optical fibers. In result blue up-conversion emission in double-clad optical fiber with Yb³⁺/Tm³⁺- doped core was presented.
