| 摘要 |
The optical transmitter/receiver apparatus of the invention includes: an optical fiber for transmitting/receiving an optical signal therethrough; and a first base including mutually spaced optical signal transmitting and receiving regions and a fiber end supporting region located between the optical signal transmitting and receiving regions. A semiconductor laser device for emitting the optical signal to be transmitted is secured to the optical signal transmitting region of the first base. A fiber end supporting portion for supporting one end of the optical fiber, to which the optical signal emitted from the semiconductor laser device is incident, is formed in the fiber end supporting region of the first base. A second base for supporting the body of the optical fiber is secured to the optical signal receiving region of the first base. A reflective filter for transmitting the optical signal to be transmitted, emitted from the semiconductor laser device, and for reflecting the optical signal to be received, incident through the other end of the optical fiber, is supported by being inserted into the second base and the body of the optical fiber. A light-receiving device for receiving the optical signal to be received, reflected by the reflective filter, is secured to the second base.
