摘要
Three kinds of electro-optic devices composed of the inverted domains in LiNbO3 substrates were fabricated. The devices are induced and controlled by applying ail electric field. The three devices are: (i) a cylindrical lens with an aperture of 340 mu m 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 degrees, depending on an electric field of 750 V/mm.
