Fabrication of Low-Loss IR-Transmitting Ge30As10Se30Te30 Glass Fibers

Abstract

Improved purification and processing techniques have been utilized to fabricate Ge30As10Se30 Te30glass fibers with a minimum loss of 0.11 dB/m at 6.6 µm. This is the lowest loss reported for any telluride glass fiber in the infrared region. Furthermore, the fibers exhibit less than 1 dB/m loss between 5.25 and 9.5 µm. © 1994 IEEE. All rights reserved.
