    • PROBLEM TO BE SOLVED: To provide an optical waveguide with a light-emitting device, in which the width of a main input path from the light-emitting device is narrow and the intensity of light beams emitted from a plurality of branches is high. SOLUTION: The optical waveguide 10 with a light-emitting device includes branched points 16 sequentially provided in a guiding light direction 17 of a main path 14, and the width of the main path 14 becomes narrower as the main path 14 moves away from the light-emitting device 11. The optical waveguide 10 with the light-emitting device of this structure can reduce a width W1 because there is no space (cladding layers) between adjacent branched paths 15. Further, the optical waveguide 10 has excellent optical transmission efficiency because the branched paths 15 are short, resulting in high intensity of light emitted. Uniformity of the light emitted is equal to or more than that of a conventional optical waveguide with a light-emitting device. COPYRIGHT: (C)2010,JPO&INPIT
    • 要解决的问题:为了提供一种具有发光器件的光波导,其中来自发光器件的主输入路径的宽度窄,并且从多个分支发射的光束的强度为 高。 解决方案:具有发光装置的光波导10包括在主路径14的引导光方向17上顺序地设置的分支点16,并且主路径14的宽度随着主路径14移开而变窄 具有这种结构的发光装置的光波导10由于在相邻的分支路径15之间没有空间(包层)而能够减小宽度W1。此外,光波导10具有优异的光学 传输效率因为分支路径15短而导致发出的高强度光。 所发射的光的均匀度等于或大于具有发光装置的常规光波导的均匀性。 版权所有(C)2010,JPO&INPIT
