Paper Abstract

The process of holographic recording based on a direct formation of periodic surface relief in AsxSe1-x (0 ≤ x ≤ 0.5) and As2S3 layers was investigated by in situ AFM depth profiling and compared with data on diffraction efficiency η of the similar relief holographic gratings, measured in a reflection mode. It is established, that the time (exposure) dependence of η has at least two components, which are connected with different components of the surface deformation Δd and relief formation up to the giant, Δd/d >10% changes in the best As0.2Se0.8 or As2S3 compositions. Correlation is found between light and e-beam induced surface deformations during recording in similar compositions. Applications for prototyping phase-modulated optoelectronic elements are considered.
