Paper Abstract

Arsenic is introduced into the tellurium halide based glasses by substituting Se or Te. Glass transition temperature, Tg, is significantly increased and Tg as high as 150 degree(s)C has been obtained. These new glasses still have a multiphonon absorption situated in the region of 18 micrometers and they still have potential low losses in the 8 - 12 micrometers region. The first optical fibers obtained from these glasses show an attenuation of about 5 dB/m in the second atmospheric window and the losses are due to defects in the fibers.
