Abstract:
An optical transmitter/receiver apparatus comprising:an optical fiber for transmitting an optical signal to be transmitted and receiving an optical signal to be received therethrough; a first base including an optical signal transmitting region and a fiber end supporting region; a semiconductor laser device, secured to the optical signal transmitting region of the first base, for emitting the optical signal to be transmitted; fiber end supporting means, formed in the fiber end supporting region of the first base, for supporting one end of the optical fiber, the optical signal to be transmitted that has been emitted from the semiconductor laser device being incident onto the end of the optical fiber; a second base, secured to the first base, for supporting a body of the optical fiber; a reflective filter, supported by being inserted into the second base and the body of the optical fiber, for transmitting the optical signal to be transmitted that has been emitted from the semiconductor laser device, and for reflecting the optical signal to be received that has been incident through the other end of the optical fiber; and a light-receiving device, secured to the second base, for receiving the optical signal to be received that has been reflected by the reflective filter, wherein the first base comprises optical-axis-direction positioning means for regulating a position of the one end of the optical fiber in an optical axis direction, and wherein the optical-axis-direction positioning means is composed of a notch portion extending vertically to the optical axis, and a fiber stopper, which is the wall face of the notch portion closer to the optical signal transmitting region.
