“…Unlike the "double-crucible" approach to ChG fiber drawing [46,47], in which the fiber is drawn from two melts of the core and cladding glasses in an inert atmosphere, we draw our fibers from a preform in the ambient environment. We produced three preforms.…”

We report the results of systematic measurements of the group velocity dispersion (GVD) in chalcogenide glass (ChG) bulk samples, composite ChG fibers, and robust high-index-contrast nanotapers. The composite ChGpolymer fibers are drawn from an extruded multimaterial preform incorporating a thick built-in polymer jacket that is thermally compatible with the ChG used, and the nanotapers are then produced without removing the polymer. We isolate the contributions of material and waveguide GVD to the total dispersion in the nanotapers and support the results with finite-element simulations. These results indicate many possibilities for dispersion engineering and nonlinearity enhancement in all-solid index-guiding ChG fibers stemming from the flexibility of this fiber fabrication methodology.

“…Tellurium-based chalcogenide glasses are of growing interest because of their large transparency in the infrared range [1][2][3] that allow for example, CO 2 detection [4]. They are also very interesting for their thermo-mechanical or electrical properties [5,6].…”

“…Chalcogenide glasses from the Te-As-Se ternary system are of considerable interest because of their large transparency in the infrared (IR) range as well as their thermo-mechanical properties which allow the glass to be drawn into fibres [1][2][3]. Among the Te-As-Se ternary systems, the Te 2 As 3 Se 5 (TAS) glass composition presents excellent rheological and optical properties in the mid-IR and is therefore commonly used in bio-sensor applications such as for medical and environmental monitoring [4,5].…”

Mechanical properties of chalcogenide glass fibres from the system Te–As–Se have been investigated as a function of environment (ageing in air, under vacuum and under static stress) through a series of tensile strength measurements. It is shown that the surface quality has a decisive effect on the tensile strength of the fibre. Surface degradation due to air oxidation induces a noticeable decrease in strength. However, a series of mechanical tests performed on fibres preserved in vacuum indicate that structural relaxation of the chalcogenide glass also plays a preponderant role in the loss of mechanical strength. Indeed the trend in mechanical properties correlates well with calorimetric characterizations performed on these glasses. Finally, it is observed that the application of a long-term static stress along the fibre induces a net increase in the tensile strength. These effects are associated with a partial alignment of the chalcogenide chains present in the glass structure. This is consistent with the observation of a longitudinal permanent deformation of these fibres under static stress.
