“…Some of the main thermal and optical properties of GeSe4 and GeTe4 glasses are gathered in Table 1. However, glass compositions from the Te-rich side of the pseudo binary GeSe4 -GeTe4 being difficult to process, single material fibers are hardly obtained and exhibit high losses (>10 dB/m), far from requirements for SC generation and other applications [23,22,24]. Consequently, we focused our work on the Se-rich part of the pseudo-binary ( Fig.1).…”

“…The studied compositions belong to the Ge-Se-Te ternary system for both core and cladding glasses. This system has already been studied for optical fibers preparation [22,23,24,25] and thin films [26]. Despite the fact that previous works explored the full ternary diagram especially for thin films, to the best of our knowledge, no result about low-losses (<5dB/m) step-index fibers has been yet reported.…”

Mid-infrared supercontinuum generation from 2 to 14 μm in arsenic- and antimony-free chalcogenide glass fibers

et al. 2019

We demonstrate the fabrication of arsenic-and antimony-free chalcogenide glasses compatible with glass fiber processing. Optical fibers with distinct index profiles are presented and characterized, namely single material fibers with or without a suspended core and standard step-index fibers with varying core diameter. In addition, we evidence their potential for nonlinear photonic devices in the mid-infrared spectral region by means of supercontinuum generation experiments in the femtosecond regime. Spectral broadenings are obtained, extending on several octaves in the mid IR from 2 to 14 µm.

“…However, while selenium addition appears to be very beneficial for fiber production it should also be noted that the lower mass of selenium atoms should lead to higher phonon energies and may consequently reduce the infrared optical cut-off. Figure 3 shows the attenuation curve of a Ge 21 Te 76 Se 3 glass with a ΔT = 123 °C. The minimum attenuations are as low as 7 dB/m in the 10-11 microns region.…”

“…In the fiber form, residual absorptions on the edges of the optical window play an important role, which significantly reduces the effective width of the transparency domain for transmission over long distances. Nevertheless, high purity telluride fibers permit effective low-loss transmission past 10 microns [14,[17][18][19][20][21].…”

Long-wave infrared fibers are used in an increasing number of applications ranging from thermal imaging to bio-sensing. However, the design of optical fiber with low-loss in the far-infrared requires a combination of properties including good rheological characteristics for fiber drawing and low phonon energy for wide optical transparency, which are often mutually exclusive and can only be achieved through fine materials engineering. This paper presents strategies for obtaining low loss fibers in the far-infrared based on telluride glasses. The composition of the glasses is systematically investigated to obtained fibers with minimal losses. The fiber attenuation is shown to depend strongly on extrinsic impurity but also on intrinsic charge carrier populations in these low band-gap amorphous semiconductor materials.

“…However, purely tellurium‐based glasses manifest strong tendency toward crystallization, which needs to be suppressed by addition of stabilizing elements—for example, the addition of Se, Ga, or I into the Ge–Te‐based chalcogenide matrices . In case of the As–Te telluride matrix it is customary to add Se to improve the thermal stability .…”

Differential scanning calorimetry was used to study thermokinetic behavior of (As 2 Se 3 ) 100−x (As 2 Te 3 ) x infrared glasses (seven compositions along the pseudo-binary were investigated). Glass-transition kinetics was described in terms of the Tool-Narayanaswamy-Moynihan model and the relaxation motions were interpreted using Raman spectroscopy data. The enthalpy relaxation kinetics was found to be absolutely uninfluenced by changing Se/Te ratio. On the other hand, DSC crystallization behavior changed significantly with increasing As 2 Te 3 content: Terich compositions show marked affinity toward crystallization, whereas in case of the compositions with 0-34 mol.% As 2 Te 3 crystal growth is significantly suppressed. X-ray diffraction analysis indicated presence of monoclinic As 2 Se 3 , As 2 Te 3 , and As 2 Se(Te) 3 phases. The complex crystallization behavior occurring in case of the Te-rich compositions was described by superposition of two autocatalytic kinetic signals. Based on the information from infrared microscopy the two overlapping crystallization processes can be attributed to the respective formations of spherulitic and needle-shaped crystallites. Best glass stability was identified in case of the (As 2 Se 3 ) 66 (As 2 Te 3 ) 34 composition, which appears to be a potential candidate for optic applications in the far-infrared region of the spectrum.
