1. A transmission module having a waveguide combiner/splitter for single fiber bidirectional optical data communication, the module comprising:

  • a first light source for transmitting light along a first forward channel through a first branch of a waveguide;

    a detector for receiving light along a backward channel through a second branch of the waveguide;

    a first optical fiber transverse to the forward and backward channels, the optical fiber being between the light source and the waveguide to couple the transmitted light to the first branch of the waveguide and being between the detector and the waveguide to couple the received light from the second branch of the waveguide; and

    a join-section of the waveguide, wherein the first and second branches of the waveguide merge.
