• The preparation and optical and mechanical characteristics of As(0.4)S(0.6), As(0.35)Se(0.65), and Ge(0.05)As(0.38)Se(0.57) glass fibers are reported. The fibers were prepared by the crucible method, as described by Vasiliev et al. (1988) and characterized experimentally in terms of optical losses as a function of wavelength, weak absorption, and photoinduced absorption. Fibers of diameter 400 microns and length 10-50 m are found to have mean bending strength of 500-700 MPa and minimum optical losses of 44-46 dB/km at 2.45-2.55 microns (AsS), 76-80 dB /km near 4 microns (AsSe), and 98 dB/km at 2.7 microns (GeAsSe).
