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.

摘要： A two-way optical communication module includes a main waveguide which is optically coupled to an optical fiber and directs light incident from the optical fiber to a light-receiving element and a sub waveguide which is optically coupled to the side of the main waveguide and directs light emitted from a light-emitting element to the optical fiber so as to carry out an efficient two-way optical communication by using one optical fiber without the necessity for an optical branch device. With this arrangement, it is possible to provide an inexpensive and small-sized two-way optical communication module which readily enables an integration with other elements so as to exhibit suitability for a small-scale network, and to provide a two-way optical communication link which uses the two-way optical communication module.

摘要： In a bidirectional optical communications module capable of all-dual-mode communications using a single optical fiber, interference due to internally scattered light is reduced by forming a diverging area on a periphery of a transmission lens and providing a thin film reflection mirror which collects incoming light. A inexpensive, compact bidirectional optical communications module can be offered with reduced interference between outgoing and incoming light, especially, interference due to internally scattered light.

摘要： A two-way optical communication device for use in a two-way optical communication system for transmitting and receiving an optical signal via a single optical fiber, comprises a light emitting element for generating transmitted light, a photodetector for receiving incoming light emitted from the optical fiber, and a reflection mirror made of a thin film having a high reflectance, having first and second surfaces, the first surface being opposite to the second surface. An optical member including the reflection mirror is provided closer to the optical fiber than the light emitting element. The incoming light emitted from the optical fiber is reflected by the first surface of the reflection mirror to be guided to the photodetector. The transmitted light emitted from the light emitting element or the transmitted light reflected by an end surface of the optical fiber is reflected by at least a portion of the second surface of the reflection mirror to prevent the transmitted light from entering the photodetector.

摘要： A sealing structure includes a lead frame having a light transmitting section, an optical element having an optical surface which is directed to the light transmitting section and is mounted on the lead frame in such a state that the optical element blocks the light transmitting section at its one end portion in an axis direction, and a sealing body that is formed in a region excluding an optical path and seals the optical element. By forming the sealing body in the region excluding the optical path, the light usage efficiency can be prevented from decreasing even when a material that can increase the environmental resistance is added to the sealing body. Further, since the optical element is mounted on the lead frame with its face down, the sealing structure can be easily formed even when the optical element is small-sized.
