Adhesion of glassy arsenic sulfide to quartz glass

Chalcogenide Glass Hollow-Core Microstructured Optical Fibers

“…The spectra of optical losses of prepared As 2 S 3 NCHCFs with diameter of 700 µm illustrated in Figures 10D,E are given in Figure 11 (Shiryaev et al, 2014b). The optical losses in fibers without Ga-In immersion were higher than in Ga-In immersed fibers.…”

“…To investigate the distribution of the CO 2 -laser radiation intensity over the fiber cross-section, a ZnSe lens was used to launch the radiation into the fiber, while the intensity distribution over the fiber output endface was observed with the help of an FIGURE 11 | The spectra of optical losses in prepared As 2 S 3 NCHCFs with diameter of 700 µm: (1) fiber illustrated in Figure 10D without Ga immersion; (2) fiber illustrated in Figure 10D with Ga-In immersion; (3) fiber illustrated in Figure 10E with Ga-In immersion (Shiryaev et al, 2014b).…”

“…The fiber loss spectra of as-drawn NCHCFs Shiryaev and Churbanov, 2013;Shiryaev et al, 2014a) were (Shiryaev et al, 2014b). measured by the cut-back method on a Bruker IFS-113v Fourier transform IR spectrometer.…”

“…However, the substrate chalcogenide tubes, especially based on arsenic sulfide glass, were found to crack due to the strong adhesion of chalcogenide glass to silica glass at annealing temperatures. Therefore, to determine the optimal conditions for manufacturing the perfect substrate chalcogenide tubes, the investigation of temperature dependence of chalcogenide glass adhesion to silica glass was carried out (Shiryaev et al, 2014b; , 2015). It was carried out by the steady detachment method.…”
