Abstract

The theoretical developments for the creation of light-induced metastable defects (LIMD), photodarkening and photoinduced volume expansion in amorphous chalcogenides are reviewed. Recent results for some chalcogenide glasses are presented. The magnitude and effect of PD and PVE is determined quantitatively and compared with the experimental results..

Keywords
