Numerical modelling of Tb3+ doped selenide-chalcogenide multimode fibre based spontaneous emission sources. Optical and Quantum Electronics, 49(12), Article 416. https://doi.org/10.1007/s11082-017-1255-5

A model is developed of a terbium (III) ion doped selenide chalcogenide glass fibre source that provides spontaneous emission within the mid-infrared (MIR) wavelength range. Three numerical algorithms are used to calculate the solution and compare th...

The well-known method presented by Swanepoel can be used to determine the refractive index dispersion of thin films in the near-infrared region from wavelength values at maxima and minima, only, of the transmission interference fringes. In order to e... Read More about Determining the refractive index dispersion and thickness of hot-pressed chalcogenide thin films from an improved Swanepoel method.

A time-resolved pump-probe method is used for the evaluation of non-linear optical coefficients of chalcogenide glasses from the As-S-Se and Ge-Se systems near their fundamental absorption band edges. The results are analyzed via comparison with the... Read More about Measurement of non-linear optical coefficients of chalcogenide glasses near the fundamental absorption band edge.
