Method and arrangement for the production of a logical NAND circuit, a logical invertor and the most general logic circuits in a purely optical way by means of the superposition of four-photon interaction processes

摘要

The method and the arrangement for the production of a mathematically logical NAND circuit and a mathematically logical invertor, and also the representation of the most general logical circuits in a purely optical way lies in the superposition of two four-photon interaction processes and the interconnection of such processes by the formation of a three-dimensional light beam grid with a tetrahedral structure in an optically non-linear medium.
