Abstract
We report on the possibility of strong relief grating fabrication in amorphous chalcogenide As2S3 glass using polarization modulated near bandgap light illumination. Such gratings are created using low intensity and spatially uniform light illumination. The obtained relief structures are strong, very smooth and do not require post-exposure development procedures. They are stable to the heat treatment and the uniform photo-exposure. The possible mechanism of such relief structure formation is also briefly discussed.
