Tellurite glasses are well known as excellent hosts for rare earth-based optical amplification [4], Tellurites offer a number of advantages as emission hosts over other materials because of their high refractive index [larger emission cross section, smaller mode area, and more compact devices], large emission bandwidth, low ion-to-ion cross relaxation, relative dependence of the 1.5 pm Er lifetime on concentration, and high erbium solubility, as has been demonstrated in tellurite glasses and fiber amplifiers [1, 12, 128,...
