Chalcogenide Glasses for All-optical Processing

Abstract

Abstract:Chalcogenide glasses, which contain S, Se or Te atoms combined with network forming elements such as Ge, As, Sb have the largest third order optical nonlinearity of any inorganic glass. As a result they are attractive candidates for fibre and waveguide devices for all-optical signal processing in the telecommunications bands. In this talk I will review our recent progress in alloptical devices such as regenerators, wavelength converters and other devices in chalcogenide glasses.
