Modifying binary Ga2S3-La2S3 glass by the addition of a third component.
In, 10th International Non-oxide Glass Conference, Corning, US,
To further improve the workability of Ga2S3-La2S3 (GLS) glass suitable for 1.3µm fibre amplifiers, we have studied the addition of a series of third components (both sulphides, i.e. Na2S, CaS and In2S3, and halides, LaR3, R = F, Cl, Br and I) into the binary GLS system. This paper describes the effect of various third components on the thermal, rheological and optical properties of the GLS. The structural role of each individual addition to the GLS glass was analysed upon its chemical bonding characteristics. Some modified GLS glasses show much enhanced UV transmission and greater workability for fibre fabrication.
