ABSTRACT:
An optical circuit according to the present invention includes a first beam splitter for splitting a signal light to two polarization lights, first and second optical couplers for coupling the split signal lights and local lights in each, and second and third beam splitters for coupling corresponding polarization lights supplied from the first and second optical couplers. The second and third beam splitters supply output signals to one double-balanced receiver of a polarization diversity receiver.
