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： There is featured a processing method for processing a target body that includes setting a beam area formed by a laser beam on the organic insulating film so as to be larger than an area formed by projecting a target part of an organic insulating film onto a horizontal plane. The method also includes, subsequently moving the organic insulating film toward the irradiated region of the laser beam, and terminating the irradiation with the laser beam when the end part of the target part coincides with the moving end part of the laser beam. This enables the resultant processed target surface to be smooth and free from reaction product including decomposed segments of the target body. Also featured is an optical component including an optical element having a surface that is processed according to the processing methods of the present invention.
