Title

Investigation on physical, structural and optical properties of Er3+ - doped bismuth borate glasses for optical fiber amplifier applications

Abstract

A new series of Er3+ doped bismuth borate glasses were prepared with the chemical composition of 5Bi2O3 - (65-x) B2O3 – 10ZnO - 10Pb3O4 - 10AlF3 - xEr2O3 (where x = 0.0, 0.1, 0.5, 1.0, 2.0 and 3.0 mol %) using the melt quenching technique.The prepared glasses were characterized by XRD, absorption, luminescence and decay spectral analysis. From XRD the amorphous and homogeneous nature of the prepared bismuth borate glasses was confirmed. The physical and optical properties of the prepared glass samples were determined. From the intensities of absorption bands, the Judd-Ofelt analysis has been applied to determine the intensity parameters Ωλ (λ = 2, 4 and 6) and the trend of these parameters has been observed as Ω2 > Ω6 >Ω4 and are used to calculate the various radiative parameters of the 4I13/2 → 4I15/2 emission transition of Er3+ ions. The normalized NIR emission spectra for the 4I13/2 → 4I15/2 transition of Er3+ - doped BBZPA glasses with various Er2O3 concentrations under 980 nm laser excitation were recorded in the wavelength region 1400 – 1700 nm. It has been observed that the spectra exhibited strong emission at 1530 nm corresponding to transition 4I13/2 → 4I15/2. The other relative parameters such as stimulated emission cross-section (σe ), optical gain (G), gain band width (∆G) were calculated. The recorded fluorescence decay curves of the 4I13/2 → 4I15/2 transition of the Er3+‐ doped BBZPA glasses exhibited single exponential nature upto 1.0 mol% and then turned into non-exponential for 2.0 and 3.0 mol% of Er3+ ions concentrations. These results suggest that the present BBZPAEr10 glass system could be suitable for optical amplifier applications at 1.53μm.
