The upconversion properties of Er3+/Yb3+ codoped tellurite glasses and glass fibers with D-shape cladding under 980 nm excitation were investigated. Intense emission bands centered at 531, 546 and 658 nm corresponding to the transitions Er3+: H11/22→I15/24, S3/24→I15/24 and F9/24→I15/24, respectively, were observed at room temperature. Compared with that in Er3+/Yb3+ codoped tellurite bulk glass,...
Tellurite glass is proposed as a host for broadband erbium-doped fiber amplifiers because of their excellent optical and chemical properties. A new single mode Er 3+ /Yb 3+ codoped tellurite fiber with D-shape cladding geometry is fabricated in this work. When pumped at 980nm, a broad erbium amplified spontaneous emission (ASE) nearly 100nm in the wavelength range of 1450–1650nm around...
