Abstract
Er3+ doped niobic-tungsten-tellurite glasses doped with concentration of Er3+ ion up to 3 wt% were fabricated. The effect of Er3+ doping concentration on thermal stability and optical properties was investigated in order to obtain the most suitable rare earth content for developing 1.5 mu m compact fiber amplifier pumped with a commercial telecom 980 nm laser diode. The maximum doping concentration allowed was found to be around 1.77 x 10(20) ions/cm(3), for which a broad 1.5 mu m emission spectra of 65 nm FWHM and a lifetime of 3.4 ms for the I-4(13/2) level was measured.
