Abstract
In this paper, a novel glass within system 65TeO(2)-9Nb(2)O(5)-5Li(2)O-15LiCl-5PbO-1.0La(2)O(3) in mol% doped with different x(Er2O3), where x = 0, 20000, 25000 and 30000 ppm were prepared by traditional meltquenching technique. The full width at half maximum (FWHM) of NIR emission, and life time, tau, of I-13/2 level of prepared glasses were evaluated. The glasses are characterized by a high value of FWHM of NIR emission at 1.53 mu m under excitation by wavelength 980 nm with respect to other glasses system doped by single Er3+ ions reported earlier. It is expected that the present studies will provide a roadmap to improve the performance of the WDM network emission band which is required for the EDFA. Thus, these fabricated glasses can be used as broadband fiber amplifier for the optical communication devices.
