“…For all of these reasons, it appears clearly that the choice of the getters, as well as the amount of getters used for the reactions, used has to be the result of a compromise between the reduction of the bands related to hydrogen and oxygen pollutions and the necessity to avoid as much as possible reactions involving the crucible. [29][30][31] The combination of TeCl 4 and magnesium, which has shown the best results in terms of attenuation, has been chosen as the most suitable for the realization by casting method 7 of a microstructured fiber, of which attenuation spectrum and cross section are visible in Fig. 5.…”

In the last twenty years the field of chalcogenide glasses has seen increasing interest, due to their broad transparency window in the mid-IR. Furthermore, chalcogenides are showing one of the highest nonlinear refractive indices among glasses. Due to these reasons, the development of chalcogenide microstructured optical fibers with low optical losses can allow for new breakthroughs in various research fields, e.g. new mid-IR laser sources, mid-IR spectroscopy, sensing and applications based on nonlinear effects, like supercontinuum generation. In this framework, chalcogenide glasses with the lowest possible amount of impurities are needed to minimize absorption losses. This study is focused on the attempt of eliminating the pollutants usually giving rise to absorption peaks inside the transparency windows: oxygen, hydrogen, carbon and water. Samples were prepared using a double distillation method: getters that can react with the impurities during the synthesis were added to the initial charge, and the reaction byproducts were eliminated by a two-steps distillation process. Ge 10 As 22 Se 68 was chosen as the system to study because of its nonlinear, optical and thermomechanical properties. Different combinations of chlorides (for the elimination of hydrogen and carbon) and metals (for the elimination of oxygen) were used, and the attenuation spectra of the resulting glasses were compared. The chosen chlorides are TeCl 4 , SeCl 4 , SbCl 3 , GaCl 3 ; the metals are Mg, Al, Zr, Ni. A holey fiber has been realized by casting method using the best sample, showing that the method is suitable for this composition and that the attenuation before and after the casting are comparable.

The production of chalcogenide microstructured optical fibers with low optical losses, due to the broad transparency window of these glasses in the mid-IR, can allow for new breakthroughs in various research fields, e.g. new mid-IR laser sources and mid-IR spectroscopy. In this framework, high purity chalcogenide glasses are needed in order to minimize absorption losses. In this study, Ge 10 As 22 Se 68 samples were prepared using a double distillation method, using different combinations of chlorides and metals as getters for the physico-chemical elimination of carbon, oxygen and hydrogen impurities. Comparing the attenuation spectra of the different samples, the choice of the getters seems to be indeed a significant factor in the quality of the glass. A holey fiber has been realized by casting method using the best sample, showing that the method is suitable for this composition and that the attenuation before and after the casting are comparable.

“…Results of the temperature dependence of separation tension of six chalcogenide glasses from silica glass are shown in Figure 9 (Shiryaev et al, 2015). These dependences show that the adhesion strength has the maximum near T g ± 10°C of chalcogenide glasses.…”
