摘要：
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 band-gap, glass transition temperature and third order optical nonlinearity (n(2)) 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. (c) 2008 Optical Society of America.
