Fabrication of low-loss IR-transmitting Ge/sub 30/As/sub 10/Se/sub 30/Te/sub 30/ glass fibers

Abstract

Improved purification and processing techniques have been utilized to fabricate Ge/sub 30/As/sub 10/Se/sub 30/Te/sub 30/ glass fibers with a minimum loss of O.11 dB/m at 6.6 /spl mu/m. 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 /spl mu/m.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
