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： 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.

摘要： At least one of end portions of a light-carrying core portion of a single-conductor optical fiber has an enlarged portion, which is a portion of the core portion larger than other portions of the core portion. An optical communications module includes a light emitting element which generates outgoing light, a sending lens which couples the outgoing light with an end portion of the single-conductor optical fiber, a light receiving element which receives incoming light from the single-conductor optical fiber, and a reflecting mirror which couples the incoming light with the light receiving element. The light emitting element and the sending lens are disposed so that the area in the end portion of the single-conductor optical fiber coupled with the outgoing light is at least partially included in the enlarged portion. The light receiving element and the reflecting mirror are disposed so as to receive incoming light that emerges from the end portion of the single-conductor optical fiber having the enlarged portion.

摘要： A bidirectional optical communication device satisfies a condition of θfb≦0≦θfa or θfa≦0≦θfb when θfa and θfb are angles of inclination between an optical axis of an optical fiber and transmission light after incidence with a numerical aperture NA at an outermost periphery, and θfa and θfb are expressed as the follows: θfa=Sin−1[{n0 Sin(θL+Sin−1(NA)/n0+θT)}/nf]−θT θfb=Sin−1[{n0 Sin(θL−Sin−1(NA)/n0+θT)}/nf]−θT where nf and no denote refractive indexes of a core of the optical fiber and air, respectively. The bidirectional optical communication device is capable of decreasing restraint of a transmission distance by reducing fluctuation of reception efficiency by the transmission distance and reducing interference between transmission light and reception light.

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.
