Waveguide and diffraction elements of photonic devices and structures optically induced in lithium niobate wafers with photorefractive surface layer

Abstract: Both, the optical waveguide elements and the phase diffraction structures have been formed in crystalline lithium niobate samples with surface doping by photorefractive impurities using the point-by-point exposure and the surface illumination through the amplitude mask.

Keywords: photorefractive effect, lithium niobate, point-by-point exposure, waveguide element, diffraction grating
