Abstract:The possibility of optical creation of polymer structures with a periodic distribution of the refractive index in a layer of a photopolymerizing composition, the thickness of which significantly exceeds the depth of field of the used projection system, is considered. Nonlinear wave processes in such an irreversible photorefractive medium for grating‐forming radiation are considered. Using computer simulation, modes of stable self‐channeling of closely propagating light beams have been found, as a result of whi… Show more
