The optical gates are the tools that can make it possible to create fully optical computers. In traditional versions, the optical system transmits information only between microchips. Photonic computers use light for communication. In those systems, all wires between components are replaced using optical fiber or nanotubes. Binary photonic computers are easy to make. The shadow or cut in the light means zero. And full power light means one. In the easiest models, there are two optical wires. Wire A means 1, and wire B means 0. Those photonic beams will be sent
