摘要： In an optical waveguide 10 with a light-emitting element to be used in the present invention, a core includes: a main path; and a plurality of branched paths branched at a plurality of branched points from the main path. The main path has two sides faced to each other, in which one side has a plurality of branched points and the other side does not have any branched points. The plurality of branched points are provided on a straight line substantially parallel to a light guiding direction of the main path. The width of the main path becomes narrower as the main path moves away from a light-emitting element. An angle θ formed by the other side without a branched point and the light guiding direction of the main path is 0.3 to 1.7°.

摘要： An optical waveguide of the present invention includes a light-absorptive section formed in a recess of a clad. The light-absorptive section prevents unwanted light from traveling through the clad. The light-absorptive section absorbs light at all wavelengths (infrared light, visible light, and ultraviolet light). The light-absorptive section is located adjacent to a light-receiving element. In the case where there is a light-absorptive section, cores are encircled by the thin clad and the thin clad encircling respective cores is encircled by the light-absorptive section.

摘要： There is provided an L-shaped optical waveguide device, wherein a coupled end of a first I-shaped optical waveguide has a concave portion and a coupled end of a second I-shaped optical waveguide has a convex portion. A concave-convex joint is formed by fitting the concave portion with the convex portion to couple the first and second I-shaped optical waveguides to each other. A plurality of cores which belong to the second I-shaped optical waveguide having the convex portion respectively bend approximately at a right angle near a photoelectric conversion element to be optically coupled to the photoelectric conversion element.

摘要： In an optical waveguide 10 with a light emitting device to be used in the present invention, branched points 16 are 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 a light emitting device 11. The optical waveguide 10 having this structure can reduce a width W1 because there are no portions that correspond spaces (cladding layers) among adjacent branched paths 15. Moreover, the optical waveguide 10 has an excellent optical transmission efficiency, resulting in high intensity of light emitted. Uniformity of the light emitted is equal or more than a conventional optical waveguide 60 with a light emitting device.

摘要： A resin layer 13 that flows to be extended on the surface of cores 12 and then a concave-shaped mold 16 having a vent hole 15 is pressed to discharge bubbles 14 contained in the resin layer 13 to the outside through the vent hole 15. In such a manner, the bubbles 14 remaining on the periphery of the cores 12 can be effectively reduced. As a result, a method for manufacturing an optical waveguide with high light transmission efficiency is obtained.
