Bismuth is one of the most thoroughly investigated main group elements, which has been
regarded as 'the wonder metal'because of its diverse oxidation states and profound …

Bismuth-doped optical glasses emit NIR luminescence in an ultrabroad spectral region of
1000-2000 nm. It makes Bi-doped glasses and glass optical fibers a promising active …

The current state of the art in infrared Bi-doped fiber laser research is reviewed. The relevant
fiber glass compositions and fiber technologies are introduced. Lasers operating on …

We have studied UV excitation spectra of IR luminescence in bismuth-doped glasses of
various compositions and obtained energy level diagrams of IR-emitting bismuth-related …

The mechanisms of optical losses in bismuth-doped silica glass (Bi: SiO_2) and fibers were
studied. It was found that in the fibers of this composition the up-conversion processes occur …

Multi-band transmission is one of the key practical solutions to cope with the continuously
growing demand on the capacity of optical communication networks without changing the …

Pulsed laser emission at∼ 1450 nm has a plethora of important applications in medical
diagnoses and laser therapy due to the strong absorption by water molecules. However …

The visible and near-IR absorption and luminescence bands of bismuth-doped silica and
germanosilicate fibres have been measured for the first time as a function of temperature …

Recent results demonstrate that bismuth-doped optical fibres have considerable potential as
near-IR active lasing media. This paper examines bismuth-doped fibres intended for the …
