We demonstrate a broadband As2S3-based fiber coupler operating up to the 5.4 μm wavelength range developed by using fused biconical tapering technique. During manufacturing process, real-time data monitoring of coupling ratio was at 2.64 μm. The measurement minimal excess loss less than 1 dB in 5-5.4 Also, bend numerically analyzed determine optimal geometric parameters.
In this work, we have prepared Ag-doped Ge–Ga–Sb–S glasses by a solid-state electric field-assisted (EFA) diffusion method. It has been found that large amount of silver metal can be introduced into the glass matrix. The distribution measured secondary ion mass spectrometry. Two models, i.e. thin- and thick-film models based on classic theory applied to fit experimental data. We modeling depends strongly temperature, e.g., an acceptable fitting obtained only model in case low temperature....
Solid state electric field‐assisted diffusion has been widely applied to oxide glasses make buried waveguides but rarely employed in chalcogenide glasses. We have previously fabricated Ag ‐doped Ge 20 Ga 5 Sb 10 S 65 by and studied the + concentration profiles. However, optical properties after silver were left unexplored. In this article, we use “scratch method” atomic force microscopy investigate refractive index profile of Dy 3+ glass diffusion. The obtained is very symmetric. An enhanced...
Abstract A computational fluid dynamics model of the glass fiber extrusion process is proposed and verified. The describes homogeneous non‐isothermal motion a viscous melt surrounding air in an experimental setup, taking into account interface between media movement metal rod. unclad Ge 28 Sb 12 Se 60 fibers for sensor applications are fabricated by extrusion. validation developed performed based on data, including pressure values, temperature field extruded mass outflow. Based model,...
The review was prepared based on the results of monitoring debris-flow hazard caused by rainfall in mountainous territory Republic Kazakhstan for 2023. Monitoring carried out areas Almaty, Zhetysu, Zhambyl, Turkestan, Mangistau, Abay and East regions. Ile, Kungey, Teriskey, Kyrgyz Talas Alatau, Ugam, Mangystau, Saur, Tarbagatai Altai mountains ridges are areas. Review contains a map Kazakhstan, information hydrometeorological situation debris f low occurrences during 2023...
