Abstract

Photo-stimulated interdiffusion in $a-Se/As_2S_3$ amorphous chalcogenide nano-multilayers (ANML) is known as a useful method for amplitude-phase optical relief formation besides the known amorphous–amorphous or amorphous–crystalline photo-induced structural transformations (PST) in homogeneous chalcogenide layers, but it has a relatively narrow sensitivity spectral range and small amplitude modulation. Experimental evidences of improvement of optical recording processes were obtained in Te-, Bi-, Sb-containing nano-layered structures based on $As_2S_3$ matrix. The influence of nano-structuring and combination of components on the sensitivity, type of the recorded relief is discussed.
