ABSTRACT:
A light guide configuration for serial bi-directional signal transmission includes an optical signal line for carrying electromagnetic radiation along a main direction of the line, optical accesses disposed along the main direction for coupling electromagnetic radiation in and out along a direction running substantially perpendicular to the main direction of the line, and diffusers disposed inside the optical signal line and allocated to an optical access, respectively. Each of the diffusers works in conjunction with the allocated optical access such that a portion of the radiation that is carried in the optical signal line can be coupled out of the optical signal line by the diffuser through the allocated optical access, and radiation entering through the optical access can be coupled into the optical signal line through the allocated diffuser. An optical circuit board having the configuration and a method for fabricating the optical circuit board are also provided.
