Abstract:
1. Method for passive alignment of an optoelectronic component and at least one light guide, the optoelectronic component comprising a substrate and, at least one active area on this substrate that will emit or receive this light and being optically coupled to the light guide, method in which: a support is used with opposite first and second faces, at least one hole is formed in the support, starting from the first face of this support, this hole being designed to receive one end of the light guide, the substrate is fixed to the second face of the support, the active area is then formed on the substrate facing the hole, and the end of the light guide is placed in the hole, this method being characterised in that first marks are also formed on the support, the substrate is fixed to the second face of this support and a photolithography technique is then used to form the active area of the optoelectronic component on this substrate, facing the hole, and photolithography is done using a mask comprising at least one pattern, this pattern corresponding to the active area to be formed, and also comprising second patterns such that when these second patterns and the first marks are aligned, the pattern of the mask is aligned with the hole of the support, and this mask is placed above the substrate by aligning the second patterns with the first marks.
