Abstract
A series of Ga-La-Na-S (GLNS) glasses have been investigated as candidate materials for optical fibers operating in the mid-infrared region of 2-5 mum. The GLNS system has been selected as a possible alternative to the Ga-La-S (GLS) system (based around 70Ga(2)S(3)/3OLa(2)S(3)) which, due to stability criteria, has proven difficult to fiber draw. The GLNS system was derived by substituting, into the standard GLS system, Na2S in place of La2S3. Seven glasses in total were characterized with compositions containing 0-30 mol% Na2S. Two glasses have been selected that show suitable properties to form a core/clad pair for fiber fabrication. The core glass selected has a 70Ga(2)S(3)-10La(2)S(3)-20Na(2)S mol% composition in conjunction with a 70Ga(2)S(3)-5La(2)S(3)-25Na(2)S mol% glass as the cladding. (C) 2003 Published by Elsevier B.V.
