摘要： An electronic writing device includes a light source, an image sensor, a detecting unit, table information, and a controller. The light source emits light to a recording medium. The image sensor receives the light reflected from the recording medium as image data. The detecting unit detects a light quantity of the image data received by the image sensor. In the table information, a light-quantity range and a control object for the image sensor or the light source are associated with each other. The light-quantity range is segmented into multiple threshold values. The controller controls the operation of the image sensor or the light source, every time the image sensor receives new image data, on the basis of the light quantity of the image data detected by the detecting unit and the table information.

摘要： The present invention uses a single substrate to provide a small-size optical waveguide element that requires no optical axis adjustments, can be driven at a low voltage, is excellent in light utilization efficiency, and can rapidly two-dimensionally deflect a light beam. A right-triangle upper electrode and a rectangular transparent upper electrode are formed on top of a thin-film optical waveguide formed on a conductive substrate to serve as a lower electrode, and an emission right-angled prism is secured on top of the transparent upper electrode. A voltage is applied between the upper electrode and the conductive substrate, and between the transparent upper electrode and the conductive substrate. A horizontal deflection is performed upon application of a voltage to the upper electrode and a vertical deflection is performed upon application of a voltage to the transparent upper electrode.

摘要： The invention intends to provides an optical waveguide device having a structure that satisfies the low drive voltage characteristic and the low propagation loss characteristic at the same time. The optical waveguide device contains a conductive or semiconductive lower electrode, an epitaxial or single orientational buffer layer provided on the lower electrode, an epitaxial or single orientational optical waveguide provided on the buffer layer, and an upper electrode of a conductive thin film or a semiconductive thin film, provided on the optical waveguide. The optical waveguide device is able to modulate, switch, or deflect incident light beams guided into the optical waveguide by applying a voltage between the upper electrode and the lower electrode.
