Comparative study of praseodymium additives in active selenide chalcogenide optical fibers (2018)
Journal Article
Tang, Z., Sojka, L., Furniss, D., Nunes, J., Sakr, H., Barney, E., Sujecki, S., Benson, T. M., & Seddon, A. B. (2018). Comparative study of praseodymium additives in active selenide chalcogenide optical fibers. Optical Materials Express, 8(12), 3910-3926. https://doi.org/10.1364/OME.8.003910

The choice of rare earth additive when doping chalcogenide glasses can affect their mid-infrared fiber performance. Three praseodymium additives, Pr-foil, PrCl3 and PrI3 are investigated in Ge-As-Ga-Se fibers. All the fibers are X-ray amorphous and t...

Modeling of resonantly pumped mid-infrared Pr3+-doped chalcogenide fiber amplifier with different pumping schemes (2018)
Journal Article
Shen, M., Furniss, D., Tang, Z., Barney, E. R., Sójka, L., Sujecki, S., Benson, T. M., & Seddon, A. B. (2018). Modeling of resonantly pumped mid-infrared Pr3+-doped chalcogenide fiber amplifier with different pumping schemes. Optics Express, 26(18), 23641-23660. https://doi.org/10.1364/OE.26.023641

We propose a model for resonantly pumped Pr3+-doped chalcogenide fiber amplifiers which includes excited state absorption and the full spectral amplified spontaneous emission spanning from 2 μm to 6 μm. Based on this model, the observed near- and mid... Read More about Modeling of resonantly pumped mid-infrared Pr3+-doped chalcogenide fiber amplifier with different pumping schemes.

Spatiotemporal modeling of mid-infrared photoluminiscence from Terbium (III) ion doped chalcogenide-selenide multimode fibers (2018)
Presentation / Conference Contribution
Sujecki, S., Sojka, L., Tang, Z., Barney, E., Furniss, D., Benson, T., & Seddon, A. (2018, May). Spatiotemporal modeling of mid-infrared photoluminiscence from Terbium (III) ion doped chalcogenide-selenide multimode fibers. Presented at REMAT 2018 5th International Conference on Rare Earth Materials, Wroclaw, Poland

Mid-infrared (MIR) light has numerous applications in medicine, biology, agriculture, defense and security. Therefore in many laboratories intensive research is being carried out to develop MIR light technology in order to achieve a similar level of...

Numerical analysis of spontaneous mid-infrared light emission from terbium ion doped multimode chalcogenide fibers (2018)
Journal Article
Sujecki, S., Sojka, L., Pawlik, E., Anders, K., Piramidowicz, R., Tang, Z., Furniss, D., Barney, E., Benson, T., & Seddon, A. (2018). Numerical analysis of spontaneous mid-infrared light emission from terbium ion doped multimode chalcogenide fibers. Journal of Luminescence, 199, https://doi.org/10.1016/j.jlumin.2018.03.031

In this contribution we use a numerical model to study the photoluminescence emitted by Tb3+ doped chalcogenide-selenide glass fibers pumped by laser light at approximately 3 µm. The model consists of the set of ordinary differential equations (ODEs)...
