摘　　要：Spectral characteristics of the amplified spontaneous emission (ASE) from a novel single mode Er^(3+) doped tellurite fiber with D-type cladding is reported in this letter. When pumped at 980 nm, an ASE source that has nearly a 100-nm flat FWHM bandwidth is obtained with a fiber length of 30-60 cm. Variation of ASE spectra with pump powers and fiber lengths are measured. Output power up to 2.0 mW is obtained with a launched pump power of 660 mW.Spectral characteristics of the amplified spontaneous emission (ASE) from a novel single mode Er^(3+) doped tellurite fiber with D-type cladding is reported in this letter.
