Photo-induced dissolution effect in Ag/As33S67 multilayer structures and its potential application

Thin Chalcogenide Films for Photonic Applications

“…Further, the discussed possibilities to modify the refractive index either by exposing the coatings to light or simply changing their composition within a chalcogenide system are utilizable in the production of focusing elements -microlenses or diffraction gratings (Wágner & Ewen, 2000;Saithoh et. al., 2002;Kovalskiy et al, 2006;Eisenberg et al, 2005;Teteris & Reinfelde, 2004;Freeman et.…”

Development of chalcogenide glass photoresists for gray scale lithography

“…It could be a result of silver diffusion from the unexposed to the exposed regions of the sample [25], but further experiments are needed to test this hypothesis and to prevent its formation. Relatively large concentration of Ag in the etched undoped area (Fig.…”

Photo induced optical changes in Sb/As2S3 multilayered film and (As2S3)0.93Sb0.07 film of equal thickness

“…These phenomena can be found both in uniform thin films as well as multilayered films. Among amorphous multilayers (AMLs), chalcogenide multilayers are attractive because of the potentials for tailoring the optical properties [2]. For example, photo induced diffusion in short period multilayer system is important because of its potential applications in holographic recording and fabrication of phase gratings.…”
