Abstract
In accordance with one embodiment of the present disclosure, an optical signal bidirectional transmission system comprises a bi-directional port configured to receive and output optical beams, an input port configured to receive beams and an output port configured to output beams, and only one birefringent crystal. A first beam manipulation system configured to adjust polarization of the beams, and direct the beams from the bi-directional port to the birefringent crystal. A second beam manipulation system configured to adjust polarization of the beams, and direct the beams from the input port to the birefringent crystal. The birefringent crystal is configured to direct the beams received from the first beam manipulation system such that the beams may exit the second beam manipulation system through the output port and direct the beams received from the second beam manipulation system such that the beams may exit the first beam manipulation system through the bi-directional port.
