<p><P>PROBLEM TO BE SOLVED: To provide an optical coupling device optical coupling device capable of facilitating coupling of an optical waveguide, an optical fiber and an optical element and formed inexpensively with high productivity and high yield and also with high accuracy, and to provide its manufacturing method. <P>SOLUTION: After the optical waveguide 2, in which an end face 5 is made an inclined reflecting face, is bonded and fixed to the base material of a support body 1, an abutting face 6 against a package substrate 11 is formed at a position away from the end face 5 by a prescribed distance 21. In the package substrate 11, an optical waveguide support face 12, a recessed part 13 and an abutting face 15 against the support body 1 are provided, the optical element 14 is fixed at a position away from the abutting face 15 by a prescribed distance 22. The optical coupling between the optical waveguide 2 and the optical element 14 is formed by making the principal face of the optical waveguide 2 in contact with the optical waveguide support face 12 to perform the positioning of the height direction, and then allowing to abut the abutting faces 6, 15 against each other to perform the positioning in the left-and-right direction. An abutting face of a depth direction is provided to facilitate all the positionings of three-dimensional directions by an abutting process by providing . <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
