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： In a two-way optical communication device, a rising mirror bends light transmitted from a light-emitting element in a virtually perpendicular direction to a surface of a substrate, and the light is gathered on an end of an optical fiber via a light-gathering mirror having a curved surface and is coupled to the optical fiber. Further, in the two-way optical communication device, received light, that is propagated from the optical fiber, is reflected on the light-gathering mirror and is gathered on the light-receiving element. The two-way optical communication device can transmit and receive light through a single optical fiber, causing only small loss in transmission and reception, so that light can be efficiently coupled to an optical fiber such as a POF having a large diameter.

摘要： On an outer peripheral portion of an adjusting lens holder (11), a ring-shaped first protrusion (12) is arranged to protrude to a housing (3). On an inner peripheral portion of the housing (3), a ring-shaped second protrusion (13) is arranged to protrude to the adjustment lens holder (11). The first protrusion (12) is arranged outside the second protrusion (13), an interval (B) between the both protrusions (12, 13) is smaller than a clearance (A) between the adjustment lens holder (11) and the housing (3), and the height of the first protrusion (12) is lower than that of the second protrusion (13). The minimum value of the clearance (A) is “A−B” and a space is provided between the first protrusion (12) adjacent to the clearance (A) and the housing (3). Thus, an adhesive is prevented from leaking out at the time of applying the adhesive in the clearance (A), and the space is filled with the adhesive. An optical system is prevented from breaking due to dropping impact by strongly fixing the adjusting lens holder (11) to the housing (3).
