Abstract

The irreversible photo- and thermo-induced changes in optical parameters and volume of binary and ternary Ge-As-S(Se) films are reviewed and compared with the respective reversible changes in glasses and films. The reached giant values of the studied changes in thin films from a new Ge2S3-AsS3 system are discussed and recommended for applications..

Keywords
