<p><P>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. <P>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. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
