Properties and application of germanium sulphide glass

Chalcogenide glasses, especially sulphide glasses, are becoming more and more important for the fabrication of optoelectronic devices in part because of the high nonlinearity, strong photosensitivity and other unique properties they have (1-3). Traditionally, the sulphide glasses are made in bulk form by traditional melt-quenching method in the quartz ampoule. The bulk glasses are then reprocessed to form fibre or planar waveguides. In this research work, the germanium sulphide glass has been characterized by a series of scientific methods including Raman, FT-IR, UV-VIS, DTA, SEM and XRD. From the analysis results, we can identify the properties of germanium sulphide glass which has shown the high potential for the fabrication of the germanium sulphide glass optical fibres and planar waveguides.Key results: The germanium sulphide glass properties have been characterized by SEM, Raman, FT-IR, UV-VIS, DTA, and XRD
