title: 980-nm diode-pumped Tm(3+)/Yb(3+)-codoped tellurite fiber for S-band amplification.
abstract: We report gain measurements in Tm(3+)/Yb(3+)-codoped tellurite glass fibers in the 1460-1530-nm region using a conventional 980-nm pumping scheme. The gain spectrum is dependent on the geometry of the fiber and the length owing to the superfluorescence upconversion pump scheme.
