Abstract

Nanostructure processing offers new methods for tailoring light-sensitive chalcogenide glass layers and photophysical processes to promote optical recording in these materials. Cyclic vacuum thermal evaporation of initial glasses allows layered structures to be obtained with 8-20 nm compositional modulation period, approx. 1 nm roughness of interfaces and total thicknesses up to 1 μm. It is shown that besides common features of thermal stability, optical properties in amorphous layers additional effects appear in nanostructures, connected with possible interdiffusion, stress and thermodynamical parameters change. These depend on the modulation period, type of combined materials and laser treatment or annealing conditions, influencing the resulting characteristics of the recording process.
