Optically Induced Channel Waveguide Structures with Spatial Modulation of Parameters in the Surface Layer of Lithium Niobate

摘要

Results of experimental studies of channel optical waveguide structures with spatially-modulated parameters obtained by point-by-point inducing of refractive index perturbations upon exposure to laser radiation of visible range in Y-cut LiNbO3 samples with photorefractive surface layer are presented.
