Abstract

Combination of numerous fine-electrodes with an electro-optic (E-O) material is much expected to be various optoelectronic key-devices.' However, since a metallic opaque electrode has usually been used in most of the devices reported,2' the loss of intensity due to the electrode portion is serious disadvantage. In addition, the devices with the opaque electrode are not suitable to focusing or defocusing function such as a lens. In the present paper proposed are two types of E-O lenses, i.e., an E-O zoom lens and a Fresnel-zone plate (FZP) E-O lens which consist of numerous transparent fine-electrodes on a flat E-O material, and are experimentally demonstrated by composing the E-O lenses with the ITO transparent electrodes on a PL7T (9/65/35) ceramic plate, in comparison with theoretical calculations.
