Abstract:
1. An optical wiring substrate comprising: a multilayer substrate; a plurality of N input optical wiring structures on an input side of said multilayer substrate, each of said input wiring structures having N input terminals formed on one face of said multilayer substrate; and a corresponding plurality of N output optical wiring structures on an output side of said multilayer substrate, each of said output optical wiring structures having N output terminals formed on another face of said substrate such that said output terminals are orthogonalized with said input terminals on said substrate, each input terminal of each of said plurality of input optical wiring structures being connected with an output terminal of one of said plurality of output optical wiring structures across different layers of said multilayer substrate at an interlayer transfer portion, wherein the input terminals of each input optical wiring structure are respectively connected to output terminals of different output optical wiring structures.
