An electron emitting element (1) includes a substrate (2), an upper electrode (3), and a fine particle layer (4) sandwiched between the substrate (2) and the upper electrode (3). The fine particle layer (4) includes metal fine particles (6) with high resistance to oxidation, and insulating fine particles (5) larger in size than the metal fine particles (6). The electron emitting element (1) can steadily emit electrons not only in vacuum but also in the atmosphere. Further, the electron emitting element (1) can work without electric discharge so that harmful substances such as ozone, NOx, or the like are scarcely generated. Accordingly, degradation of the electron emitting element (1) due to oxidation does not occur. Therefore, the electron emitting element (1) has a long life and can steadily work continuously for a long period of time even in the atmosphere.

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.

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.
