摘要:
An optical receiver of a bidirectional optical communication module is fabricated through an assembling process in which multiple modules are assembled concurrently. The module includes a first substrate formed with a groove, an optical fiber located in the groove and having a flat surface, a reflective filter inserted between the first substrate and the fiber with a predetermined inclination angle in order to reflect an incident optical signal, a second substrate supporting the fiber and mounted on the first substrate such that the flat surface.

A bidirectional optical transmission/reception module includes a sub-mount and a plane optical device that is mounted on the sub-mount for transmitting and receiving an optical signal. The module includes an optical fiber for inputting the optical signal from and outputting the optical signal to the outside of the bi-directional optical transmission/reception module. A stub into which the optical fiber is mounted protrudes conically at one end adjacent to the device to point the fiber end toward and planarly in alignment with the device. A support member has a hole formed at its one upstanding side, and the hole is penetrated by the conical end of the stub.

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.
