    • A coupling system for the output light of a semiconductor laser, characterized in that an end portion of an optical fiber is made as a focusing lens to be coupled with the output light from an active layer of the semiconductor laser is formed so that, at least in a plane parallel to the optical axis of the output light and perpendicular to the junction plane of the semiconductor laser, the width of the end portion continuously decreases towards its tip to provide a required curvature at the tip and that the distribution of light of the semiconductor laser and that of the optical fiber and the focusing lens are matched with each other in the plane perpendicular to the junction plane of the semiconductor laser. The end portion of the optical fiber defining the focusing lens may be formed to have a fixed width in a plane parallel to the junction plane of the semiconductor laser. The end portion of the optical fiber or focusing lens may be formed so that it has a required curvature in a plane parallel to the plane of junction of the semiconductor laser and that the distribution of light of the semiconductor laser and that of the optical fiber and focusing lens are matched with each other also in a plane parallel to the junction plane of the semiconductor laser.
    • 一种用于半导体激光器的输出光的耦合系统,其特征在于,将光纤的端部制成为与来自半导体激光器的有源层的输出光耦合的聚焦透镜,使得至少 在平行于输出光的光轴并且垂直于半导体激光器的结面的平面中,端部的宽度朝向其尖端连续地减小,以在尖端处提供所需的曲率,并且, 半导体激光器和光纤和聚焦透镜的半导体激光器在垂直于半导体激光器的结面的平面中彼此匹配。 限定聚焦透镜的光纤的端部可以形成为在平行于半导体激光器的接合面的平面中具有固定的宽度。 光纤或聚焦透镜的端部可以形成为使得其在平行于半导体激光器的结的平面的平面中具有所需的曲率,并且半导体激光器和光纤的光分布 聚焦透镜在平行于半导体激光器的结面的平面中彼此匹配。

    • A display device is provided that can eliminate feeling of discomfort of a user while preventing cost from being increased. The display device includes display means 1, control means 3 that causes the display means 1 to display predetermined display information and updates the display information at a predetermined display update cycle (timing), illumination means 2 that illuminates the display means 1, and dimming means 4 that changes brightness of the illumination means 2. The control means 3 chooses the brightness of the illumination means 2 on the basis of input information from the dimming means 4 and changes the brightness of the illumination means 2 at a timing corresponding to the display update cycle for updating the display information.
    • 提供一种可以消除使用者的不适感,同时防止成本增加的显示装置。 显示装置包括显示装置1,使显示装置1显示预定显示信息并以预定显示更新周期(定时)更新显示信息的控制装置3,照亮显示装置1的照明装置2和调光装置 改变照明装置2的亮度。控制装置3基于来自调光装置4的输入信息选择照明装置2的亮度,并在对应于显示更新的定时改变照明装置2的亮度 循环,用于更新显示信息。
