Patent ID: 7794158

Claim:
A fabrication method of an optical interconnection component in which a light emitting face of an optical device is arranged and fixed on a rear surface of a substrate, an optical fiber is wired on a surface of the substrate, and a 45-degree mirror is formed on the optical fiber so that the optical fiber may be coupled optically to said optical device, comprising the steps of: forming an optical fiber holder, having at least one angulated groove to which said optical fiber is to be disposed, for directing the angulated groove in which said optical fiber is to be disposed towards said substrate and placed on the first surface of said substrate, the angulated groove having a square cross-section, wherein a width of the angulated groove is almost the same as a diameter of said optical fiber and a depth of the angulated groove is larger than a radius of said optical fiber and smaller than the diameter of said optical fiber; forming a guide on the first surface of said substrate for guiding the optical fiber holder at a position where said optical fiber and said optical device are to be coupled optically; forming said 45-degree mirror at said optical fiber by dicing said optical fiber holder and said optical fiber together at a state in which said optical fiber is disposed in said angulated groove; disposing the optical fiber holder on a surface of said substrate; guiding the optical fiber holder by said guide to the position where said optical fiber and said optical device are to be coupled optically, and fixing their relative position, and wherein the optical fiber and the optical fiber holder are fixed to the substrate by means of a bonding material with a refractive index smaller than a refractive index of a cladding of said optical fiber, and a spatial gap between a bank of said optical fiber holder and said substrate is filled by said bonding material.
