Abstract

Chalcogenide glasses are low phonon energy materials and hence are transparent from the visible up to the infrared. These glasses are susceptible to electromagnetic radiation and show a wide variety of photoinduced effects as a result of illumination These photoinduced effects can boused to fabricate diffractive as well as waveguide structures in these glasses [1,2]. Up to now thermally evaporated and sputtered films have been mainly used for fabrication of these structures in chalcogenide glasses.
