Abstract
Three kinds of electro‐optic devices composed of the inverted domains in LiNbO3 substrates were fabricated. The devices are induced and controlled by applying an electric field. The three devices are: (i) a cylindrical lens with an aperture of 340 μm and length of 10 mm, which can tune the focusing length from 20 to 50 mm depending on an electric field ranging from 250 to 150 V/mm, (ii) an optical switching device composed of a periodically inverted domain structure, which can reflect the whole power of an incident light beam by applying an electric field of 700 V/mm, and (iii) a deflection device with a deflection angle of about 5°, depending on an electric field of 750 V/mm.Keywords
