Abstract
In a bi-directional optical transceiver module, a first waveguide transmits a optical signal received from a light source to a high reflection layer formed on a waveguide substrate. A second waveguide extends from the optical fiber to the high reflection layer. With a first mode coupling region formed by ends of the first and second waveguides near the high reflection layer, the second waveguide transmits the transmission optical signal mode-coupled from the first waveguide to the optical fiber and receives the reception optical signal from the optical fiber. A third waveguide extends from the optical detector to near an end of the optical fiber. With a second mode coupling region formed by an end of the third waveguide and the other end of the second waveguide, the third waveguide transmits the reception optical signal mode-coupled from the second waveguide to the optical detector.
