    摘要： Disclosed is inexpensive optical waveguide for an optical connector which is accurately positioned across the width of cores when inserted in and fixed in an optical waveguide fixing through hole of a ferrule to provide low optical coupling loss when connected, an optical connector using the same, and a method of manufacturing the same. An optical waveguide for an optical connector includes cores, an under cladding layer, and an over cladding layer. The strip-shaped optical waveguide has a longitudinal end portion configured to be fixed in a predetermined through hole provided in a ferrule of an optical connector. The cores are formed on the under cladding layer by a photolithographic method. The over cladding layer is formed with respect to the positions of the cores or positioning alignment marks by a photolithographic method. The over cladding layer covers the cores, and the under cladding layer including crosswise end surfaces thereof.

    摘要： A manufacturing method of an optical waveguide device and an optical waveguide device obtained thereby. An under cladding layer is formed on the front surface of a colored-layer-coated PET substrate including a PET substrate portion and a colored layer of a color that absorbs irradiation light and formed on the back surface of the PET substrate portion, and then a photosensitive resin layer for the formation of cores is formed thereon. In forming the cores, when the irradiation light reaches the bottom surface of the PET substrate portion, most of the irradiation light is absorbed by the colored layer, so that there is little irradiation light reflected from the bottom surface of the PET substrate portion. This significantly reduces the irradiation light reflected diffusely from the PET substrate portion and reaching the photosensitive resin layer to thereby effectively suppress the surface roughening of the side surfaces of the cores.
