Absorption and emission cross section of Yb3+ ions in Al2O3 and P2O5 doped fibers
M. A. Melkumov, I. A. Bufetov, K. S. Kravtsov +2
The results of measurements of the emission and absorption cross section for the transition 2F5/2 -> 2F7/2 of Yb3+ ions in Al2O3 and P2O5 doped silica fibers are presented. Differe…
Infrared luminescence in Bi-doped Ge-S and As-Ge-S chalcogenide glasses and fibers
V. G. Plotnichenko, D. V. Philippovskiy, V. O. Sokolov +4
Experimental and theoretical studies of spectral properties of chalcogenide Ge-S and As-Ge-S glasses and fibers are performed. A broad infrared (IR) luminescence band which covers…
Near-IR luminescence in bismuth-doped AgCl crystals
V. G. Plotnichenko, D. V. Philippovskiy, V. O. Sokolov +4
Experimental and computer-modeling studies of spectral properties of crystalline AgCl doped with metal bismuth or bismuth chloride are performed. Broad near-IR luminescence band in…
Near-infrared luminescence in bismuth-doped TlCl crystal
V. G. Plotnichenko, V. O. Sokolov, D. V. Philippovskiy +3
Experimental and theoretical studies of spectral properties of crystalline TlCl:Bi are performed. Two broad near-infrared luminescence bands with a lifetime about 0.25 ms are obser…
Mid-infrared supercontinuum generation in tapered chalcogenide fiber for producing octave-spanning frequency comb around 3 μm
Alireza Marandi, Charles W. Rudy, Victor G. Plotnichenko +3
We demonstrate mid-infrared (mid-IR) supercontinuum generation (SCG) with instantaneous bandwidth from 2.2 to 5 μm at 40 dB below the peak, covering the wavelength range desirable…
Thermal behavior of NIR active centers in Bi-doped optical fibers
D. A. Dvoretsky, I. A. Bufetov, V. V. Vel'miskin +6
The temperature dependences of optical loss and luminescence spectra have been measured in visible and NIR spectral range for Bi-doped silica and Bi-doped germanosilicate fibers fo…
