Thulium-doped tellurite glasses for S-band amplification

Role of PbO substitution by Bi2O3 on 1.47μm luminescence properties of Tm3+/Tb3+-doped Bi2O3–GeO2–Ga2O3 glass

“…The calculated peak emission cross-section and measured lifetime is expressed as peak e and f , respectively. in BPGG glasses are much higher than those of tellurite (3.339 × 10 −26 ) [24] and ZBLAN (1.368 × 10 −26 ) [25] glass. This might benefit from the higher refractive index of BPGG glasses.…”

Spectroscopic and structural characterization of transparent fluorogermanate glass ceramics with LaF3:Tm3+ nanocrystals for optical amplifications

“…Besides, the r  FWHM of GC0.3Tm around 1.46 lm is found to be larger than that of ZBLAN glass (1.36  10 À26 cm 3 ) [28], but less than that of chalcogenide (3.64  10 À26 cm 3 [13]) and Ga 2 O 3 -Bi 2 O 3 -PbOGeO 2 (5.11  10 À26 cm 3 ) glasses [6]. The results suggest that the fluorogermanate glass ceramic could be a useful host for amplifiers in the 1100-1300 nm and 1300-1550 nm regions.…”

Fabrication and emission properties of Er3+/Yb3+ codoped tellurite glass fiber for broadband optical amplification

“…Since then, mass-works have been done mostly on spectroscopic properties of tellurite glasses and fibers doped with rare earth ions [1][2][3][16][17][18]. Methods for broadening, as well as flattening the amplification bandwidth of Er 3+ -doped tellurite fibers (EDTF) are very important in increasing the transmission capacity of wavelength-division multiplexed telecommunication systems.…”
