Abstract
A series of GaLaNaS (GLNS) glasses have been investigated as candidate materials for optical fibres operating in the mid-infrared region of 2-5mum. The GLNS system has been selected as an possible alternative to the GLS system (based around 70 Ga2S3/30 La2S3) which, due to stability criteria, has proven difficult to fibre draw. The GLaS system was derived by substituting, into the standard GLS system, Na2S in place of La2S3. Seven glasses in total were characterised with compositions containing 0 to 30 mol% Na2S. Two glasses have been selected that show suitable properties to form a core/clad pair for fibre fabrication. The core glass selected has a composition with higher La2S3 content than the cladding glass, which has increased Na2S3 content. Subsequent extrusion trials using this glass pairing have been conducted.
