Paper 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, Ppump=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 I482nm/I545nm luminescence intensity ratio is much higher than in bulk glass.
