| 摘要 |
An electro-optical device such as an optical deflector comprising a ferro-electric substrate, electrodes provided on principal surfaces of this substrate and an inverted domain having a polygonal, e.g. triangular shape formed in the substrate, at least one of the domain walls of these domains being effectively perpendicular to the principal surfaces of the substrate, and a light beam passing through at least two of the domain walls, thus permitting fast random access, wide deflection angle and high resolution. <IMAGE> |
