Abstract
A fiber optic repeater comprising a substrate of electro-optically sensitive material and an optical waveguide formed in the surface of the substrate and extending between longitudinally opposite edge portions of the substrate. The waveguide includes longitudinally opposite end portions each having a terminal face exposed at one of the edge portions of the substrate and a pair of laterally spaced-apart central portions joined to each of the end portions. The waveguide propagates the optical signals between the exposed terminal faces. First and second data branches are formed in the surface of the substrate to divert a portion of the optical signal being propagated by the waveguide before the signal enters the central portions of the waveguide. Each data branch has a connecting portion extending from an end portion of the waveguide and an output end opposite the connecting portion. A photodetector is coupled to the output end of each data branch to detect the portion of the optical signals diverted by the respective data branch. A system including a plurality of optical repeaters each having the capability to receive data from and transmit data to an optical fiber data bus also is disclosed.
