Abstract
An optical bus for propagating signal light comprises a beam dividing portion consisting of a plurality of diffraction surfaces for diffracting signal light input from a signal light input portion and directing it toward a plurality of signal light output portions, which are arranged in a mosaic manner. A signal processor uses the above optical bus to carry out signal processing including the transmission and reception of a signal to improve optical energy use efficiency, thereby reducing power consumption and constructing a system having extendability.
