摘要： An optical fiber includes an entrance face that is optically coupleable with a device for transmitting a light beam through the optical fiber. The entrance face includes a core region and a cladding region surrounding the core region. The cladding region is at least partially covered with a coating, which is made of metal, for example. That is, the coating is formed over a whole area of the cladding region or the coating is formed on an area of the cladding region defined in a vicinity of the core region. The coating has a mirror surface to increase the reflectivity thereof and enhances the reflectivity of the entrance face.

摘要： An optical communication device includes a light source that emits a light beam for transmitting data, and an optical fiber that has an entrance face through which the light beam emitted from the light source enters the optical fiber. The entrance face has a core region and a cladding region. A beam spot moving mechanism moves a beam spot formed by the light beam emitted from the light source on the entrance face of the optical fiber in first and second directions. A light detector having a light receiving surface detects light amount of the light beam reflected by the entrance face of the optical fiber. The light receiving surface is divided in multiple light detecting areas. A controller controls the beam spot moving mechanism to adjust light amounts detected by the light detecting areas to a predetermined ratio. For example, the controller controls the beam spot moving mechanism so that the light amounts detected by the light detecting areas become the same.

摘要： There is provided an optical communication apparatus, which is provided with a light emitting device that emits a transmission light signal modulated with transmission data, an optical fiber, and a deflecting system that is located between the light emitting device and the optical fiber so as to move a position of the transmission light signal on an entrance surface of the optical fiber. The optical communication apparatus is further provided with a feedback control system that controls the deflecting system so as to move the position of the transmission light signal to a center of a core of the optical fiber based on intensity of a portion of the transmission light signal.
