| 英文摘要 | Bidirectional optical communication devices are attached to both ends of an optical fiber, and each of them has a transmitting light wave guide coupled to a semiconductor laser and a received light wave guide which is coupled to a photodiode, and optically separated from the transmitting light wave guide. On the end face of the light-incident area of the optical fiber on which transmitting light coupled to the optical fiber from the transmitting light wave guide is directed, the light axis of the transmitting light is set so as to tilt with respect to the normal to the end face of the light-incident area so as to prevent reflected light on the end face of the light-incident area caused by the transmitting light from entering the photodiode installed on the same side as the semiconductor laser. Consequently, light communication is simultaneously carried out bidirectionally in a stable manner by using a single optical fiber; thus, it is possible to provide a bidirectional optical communication device and a bidirectional optical communication apparatus using this device at low costs. |
