Germanium oxide (GeO2) and tellurium oxide (TeO2) based glasses are classed as the
heavy metal oxide glasses, with phonon energies ranging between 740cm− 1 and 880cm …

Fiber-optic multi-band transmission (MBT) aims at exploiting the low-loss spectral windows
of single-mode fibers (SMFs) for data transport, expanding by the available bandwidth of C …

Lanthanide components are constituents of major importance in the chemistry of non-oxide
glasses. Even though they cannot form glasses by themselves, lanthanides may enter the …

Multi-band (MB) optical transmission promises to extend the lifetime of existing optical fibre
infrastructures, which usually transmit within the C-band only, with C+ L-band being also …

We compare the networking merit of two possible multiplexing techniques on top of
wavelength division multiplexing to enlarge transmission capacity: the band division …

The combination of multi-band optical transmission and ITU-T G. 654 loss-minimized large-
effective-area fibers enables superior network performance in the low-loss C+ L wavelength …

This paper describes in detail the amplification characteristics of gain-shifted thulium-doped
fiber amplifiers (GS-TDFAs) operating in the 1480-to 1510-nm wavelength region (1.49-µm …

Three thulium doped tellurite glass compositions have been investigated. The 1470 nm
transition is radiative in these tellurite glasses and the radiative lifetimes are in the range of …

The ITU-G. 652D is the most deployed optical fiber worldwide and presents a wide low-loss
window with negligible water absorption peak. Multi-band systems exploit this characteristic …

The spectroscopic properties of Tm^ 3+/Yb^ 3+ co-doped silica fibers under excitation at 980
nm are reported. Three distinct up-conversion fluorescence bands were observed in the …
