ABSTRACT:
In a communication system using a sheet light guide10which is formed in a manner that the sheet light guide contains light-scattering particles in a sheet optical medium, and propagates a signal light incident from one end surface thereof to the other end surface side to which a photodetector is coupled, while scattering the signal light by the particles, at least two of the sheet light guides10are coupled to each other with an angle-converting light guide90interposed therebetween.
