Abstract
Core–clad single-mode optical fibers based on high-purity TeAsSe glasses prepared by chemical and physical methods of purification have been drawn. The “build-in casting” and “rod-in-tube” techniques were used to form the high ratio of core/cladding diameters. The minimal optical losses measured by cut-back method were 0.33 dB/m at 7.5 μm for TeAsSe glass fiber with core diameter of 20 μm and cladding diameter of 450 μm. The optical losses in the spectral range between 9 and 11 μm were equal to 1–3 dB/m.
