<p><P>PROBLEM TO BE SOLVED: To provide an optical coupling device in which an processing error produced at the time of processing an optical waveguide to expose a core end part thereof is not contained in an alignment error of the optical waveguide core end part and other optical components, and to provide an optical waveguide permitting to manufacture such an optical coupling device. <P>SOLUTION: The optical waveguide 1 is a united body of clads 2, 4 and a core 3 as a light guide. An end face 6 of the optical waveguide 1 is formed into a reflecting surface inclined at about 45 degrees by dicing processing, and the optical waveguide 1 is optically coupled to an optical element 26 via reflection by the inclined end face 6. By similar dicing processing, a V-groove 8 for a position alignment marker is formed at a position a predetermined distance 9 off the upper end 7 of the inclined end face 6 of the optical waveguide 1 upper part, and the optical waveguide 1 is accurately positioned to a supporting body 11 by concavo-convex engagement using the V-groove 8. The supporting body 11 is provided with a means for position alignment with a mounting substrate mounted with the optical element 26 at the position a predetermined distance off the concavo-concave engagement position. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
