About
My research focuses on the development of chalcogenide glasses for infrared device application. I work on the synthesis of chalcogen-based systems using melt quench technique which includes removal of extrinsic impurities by distillation process. I conduct detailed thermal, optical and structural studies to understand the structural relaxation of glasses. I investigate bandgap, disorder and defect states and support the examined properties by the local structural units determined by Raman spectroscopy.
Currently, I am working on the investigation of structural properties of IR transparent optical fibres for Lasing and medical applications.
