1Spatiotemporal modeling of mid-infrared photoluminescence from terbium(Ⅲ) ion doped chalcogenide-selenide multimode fibers显示文摘A numerical model was developed to study the time dynamics of photo luminescence emitted by Tb^3+doped multimode chalcogenide-selenide glass fibers pumped by laser light at approximately 2μm.The model consists of a set of partial differential equations(PDEs),which describe the temporal and spatial evolution of the photon density and level populations within the fiber.In order to solve numerically the PDEs a method of lines was applied.The modeling parameters were extracted from measurements and from data available in the literature.The numerical results obtained support experimental observations.In particular,the developed model reproduces the discrepancies that are observed between the photoluminescence decay curves obtained from different points along the fiber.The numerical analysis was also used to explain the source of these discrepancies.Slawomir Sujecki Lukasz Sojka Zhuoqi Tang Dinuka Jayasuriya David Furniss Emma Barney Trevor Benson Angela Seddon 2019Journal of Rare Earths2019,37,11:0
