摘要： The present invention provides a small optical waveguide structure capable of converting the spot size of light, and capable of reducing the conversion loss when compared under the condition of the same waveguide length and performing an optical conversion with high efficiency. An optical waveguide structure (100) includes a base waveguide (110) including a taper section (111) whose width becomes continuously narrower from one side toward another side, and a narrow-width section (112) that is consecutively connected to a narrow-width side of the taper section (111) and extends toward the another side. In the optical waveguide structure (100), at least three-layered upper waveguides (121 to 123) each of which has a planar shape smaller than the taper section (111) and includes a planar-view-roughly-wedge-shaped section whose width becomes continuously narrower from the one side toward the another side at least on a tip side are stacked above the taper section (111) of the base waveguide (110) in such a manner that the planar shape becomes successively smaller from the base waveguide side (110).

摘要： An optical waveguide type optical terminator forms an optical waveguide structure including at least an optical absorption core (103) which is formed on a clad layer (102) and includes a portion composed of silicon in which an impurity of 1019 cm−3 or more is doped, and is used by being optically connected in series with an optical waveguide including a core (105) composed of silicon. The optical absorption core (103) is sufficient provided that, at least, an impurity of around 1019 cm−3 is doped therein. For example, its impurity concentration is sufficient provided that it falls within a range of 1019 -1020 cm−3. The existence of this impurity causes absorption of light in the optical absorption core (103).

摘要： A communication terminal shares data with another communication terminal. The communication terminal includes circuitry. The circuitry receives, from a communication management apparatus that manages the data shared with the another communication terminal, storage location information representing a storage location of background image data transmitted from the another communication terminal, and transmits a download request to an image storing apparatus corresponding to the storage location to request download of the background image data. The circuitry further starts downloading the background image data from the image storing apparatus and receives, from the communication management apparatus, stroke data of a stroke image rendered on the another communication terminal.

摘要： When a control code detection unit detects a control code, an image storage unit stores the image data of pages that are entered after the page with the control code added thereto. A control code decision unit decides the content of control for the output processing of the image data based on all the control codes detected by the control code detection unit. Then, based on the content of control decided by the control code decision unit, a control unit controls the output processing of the image data stored in the image storage unit.
