Thin-Film Optical Elements Based on Chalcogenide Materials

Thin-film components based on chalcogenide layers will be demonstrated. These component include volume diffractive optical elements based on photo-induced refractive index change or silver photodissolution in As 2 S 3 layers and ultra-uniform bandpass filters based on photosensitive chalcogenide spacers. Theoretical study and design, experimental demonstration and final complete characterization of various optical elements will be presented.
