Abstract
A multilayer PCB () for optical transmission is presented. The multilayer PCB includes a first layer (), a second layer (), and a transparent layer () between them. The transparent layer may have a first compartment (), which may have a first mirror () operable to reflect a beam of light (B) into the first compartment of the transparent layer in a plurality of directions (C) perpendicular to the direction of the beam of light, thereby transmitting throughout the first compartment an optical signal carried by the beam of light in said plurality of directions such that one or more other mirrors disposed in the first compartment of the transparent layer are able to receive a beam of reflected light (C) carrying the optical signal. The multilayer PCB may further include a second mirror () in the first compartment for reflecting a wave of reflected light (C) carrying the optical signal toward an optical receiver ().
