Abstract
A data bus coupler having a fiber optic bundle input, a separate optical ulator or detector (described in a concurrent disclosure by the same inventors) attached to each fiber of the bundle for adding information to, extracting information from, or detecting the information conducted by the fiber, and an output wherein the fibers are rejoined into a fiber optic bundle. The optical modulator/detectors are double heterojunction semiconductors that are switched "on" by reverse biasing and with large voltages they may act as photoavalanche diodes when detecting incident radiation.
