Optical and physical properties of Er3+-Yb3+ co-doped tellurite fibers
2011
In this work we present results of physical and optical properties of Er 3+ -Yb 3+ co-doped tellurite glasses and fibers. The
Double Clad Tellurite Fibers (DCTFs) are based on glasses with the composition: TeO 2 -WO 3 -Nb 2 O 5 -Na 2 O-Al 2 O 3 -Er 2 O 3 -Yb 2 O 3 . The DCTFs were fabricated by using the rod-in-tube technique and a Heathway drawing tower. The optical
absorption spectra (ranging from 350 to 1750 nm) of these fibers were measured using an Optical Spectrum Analyzer
(OSA). The emission spectra, around 1550 nm band, of these fibers (lengths varying from 1 to 60 cm) were obtained by
using a 980nm diode laser pump. The optimal Amplified Spontaneous Emission (ASE) spectra were observed for fiber
lengths ranging from 2 to 6 cm. The Er 3+ /Yb 3+ co-doped DCTFs show an efficient up-conversion process in comparison
with the Er 3+ -doped DCTF.
