Abstract: This article presents the results of experimental studies of refractive index changes induced point-by-point in the surfacedoped lithium niobate crystal during the formation of channel optical waveguide structures. Refractive index changes were obtained by a focused laser beam during the crystal surface exposure and investigated using a Jamin interferometer.
Keywords: optical inducing, point-by-point exposure, lithium niobate, photorefractive effect, channel waveguides
