The local environment of Dy3+in selenium-rich chalcogenide glasses (2014)
Journal Article
Barney, E. R., Tang, Z., Seddon, A., Furniss, D., Sujecki, S., Benson, T. M., …Gianolio, D. (in press). The local environment of Dy3+in selenium-rich chalcogenide glasses. RSC Advances, 4(80), https://doi.org/10.1039/C4RA07192A

The environment of Dy3+ is investigated when it is added as DyCl3 or Dy foil into two base glasses, Ge16.5As19−xGaxSe64.5, where x = 3 or 10 at%, at doping levels between 0 and 3000 parts per million by weight (ppmw) Dy3+. Extended X-ray Absorption F... Read More about The local environment of Dy3+in selenium-rich chalcogenide glasses.

Mid-infrared supercontinuum generation to 12.5?m in large NA chalcogenide step-index fibres pumped at 4.5?m (2014)
Journal Article
Kubat, I., Agger, C. S., Møller, U., Seddon, A. B., Tang, Z., Sujecki, S., …Bang, O. (2014). Mid-infrared supercontinuum generation to 12.5μm in large NA chalcogenide step-index fibres pumped at 4.5μm. Optics Express, 22(16), 19169-19182. https://doi.org/10.1364/oe.22.019169

We present numerical modeling of mid-infrared (MIR) supercontinuum generation (SCG) in dispersion-optimized chalcogenide (CHALC) step-index fibres (SIFs) with exceptionally high numerical aperture (NA) around one, pumped with mode-locked praseodymium...

Broadband, mid-infrared emission from Pr3+ doped GeAsGaSe chalcogenide fiber, optically clad (2014)
Journal Article
Sójka, L., Tang, Z., Furniss, D., Sakr, H., Oladeji, A., Bereś-Pawlik, E., …Sujecki, S. (2014). Broadband, mid-infrared emission from Pr3+ doped GeAsGaSe chalcogenide fiber, optically clad. Optical Materials, 36(6), 1076-1082. https://doi.org/10.1016/j.optmat.2014.01.038

We present a study of mid-infrared photoluminescence in the wavelength range 3.5–5.5lm emitted from Pr3+: GeAsGaSe core/GeAsGaSe cladding chalcogenide fiber. The Pr3+doped fiber optic preform is fabricated using extrusion and is successfully drawn to...
