制作了三种由LiNbO 3衬底中的反转畴组成的电光器件。这些器件通过施加电场来感应和控制。这三种设备是：（i）具有340 μm孔径和10 mm长度的圆柱形透镜，其可以根据250 - 150 V/mm的电场将聚焦长度从20 - 50 mm调节，（ii）由周期性反转畴结构组成的光开关器件，其可以通过施加700 V/mm的电场反射入射光束的全部功率，和（iii）偏转装置，其偏转角约为5°，取决于750 V/mm的电场。
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.
