  • Compact optical splitter and combiner
    Patent number: 6501886
    Abstract: An optical splitter/combiner has a split end, i.e., input/output end that has at least a first input/output segment, a second input/output segment, a third input/output segment, and a fourth input/output segment. The optical splitter/combiner has an upper first stage junction that joins the first input/output segment and the second input/output segment, which define an upper first stage bisector. A lower first stage junction joins the third input/output segment and the fourth input/output segment, which define a lower first stage bisector. An upper intermediate segment communicates with the upper first stage junction. A lower intermediate segment communicates with the lower first stage junction. A second stage junction joins the upper intermediate segment and the lower intermediate segment to form a single input output segment. The upper intermediate segment and the lower intermediate segment define a second stage bisector.
