Abstract

In the paper the analysis of white upconversion luminescence obtained as a result superposition of emission bands in germanate glass and double- clad optical fiber co-doped with Yb³⁺/Tm³⁺/Ho³⁺ and Yb³⁺/Er³⁺/Tm³⁺ have been presented. Calculated CIE coordinates for glass co-doped with 0.5Yb₂O₃/0.4Tm₂O₃ /0.1 Ho₂O₃ were x=0.311, y=0.337, P_pump=2.5W and for 0.5Yb₂O₃/0.25Tm₂O₃ /0.25Er₂O₃ co-doped were: x = 252, y = 502. Influence of pump power on the colour coordinates have been also investigated. Thus Yb³⁺/Tm³⁺/Ho³⁺ co-dopant system in germanate glass was used as a core of double-clad optical fiber. Comparative analyses showed differences in luminescence spectra shape of bulk glass and fabricated 0.5Yb₂O₃/0.4Tm₂O₃ /0.1Ho₂O₃ triply doped double – clad optical fiber. Due to partial reabsorption of blue part of amplified spontaneous emission signal propagating band in optical fiber is shifted by 4 nm towards shorter wavelengths. Moreover the I_482nm/I_545nm luminescence intensity ratio is much higher than in bulk glass.
