Abstract

We present a systematic study of GexAsySe1-x-y bulk chalcogenide glasses to determine the best composition for fabricating alloptical devices. The dependence of physical parameters such as the bandgap, glass transition temperature and third order optical nonlinearity (n2) on composition has been studied and a relation between the bond-structure and elevated linear loss levels in high Germanium glasses has been identified. It is found that glasses with 11<x<13 % are most suitable for all-optical devices.
