Abstract
An optical calculating apparatus which can perform operations by optically controlling incident light and hence perform such operations very rapidly and in parallel is provided. A unit component is composed of a pair of electrodes and a modulation material layer sandwiched therebetween and consisting of a material such as a liquid crystal in which the molecular struture is twisted by an applied electric field to change the transmission amount and transmission direction of light incident from the outside, thereby performing a modulation. The optical calculating apparatus is constructed by stacking or laminating such unit components in n stages. The unit component of the first stage has a structure in which the modulation material layer is sandwiched between a pair of the electrodes and input light enters into the modulation material layer in the direction perpendicular to the arrangement direction of the electrodes.
