Abstract
A method of constructing an optoelectronic module for use in fiber optic communication systems. The module is adapted for mechanically and optically interconnecting with a ferrule supporting a set of optical communications fibers. The module supports an optoelectronic device comprised of a set of photoactive components for use in communicating with the fibers. The module also includes a carrier adapted for supporting the optoelectronic device and a set of guide pins used for alignment with the ferrule. The module is constructed in steps. First, the carrier constructed as a silicon substrate. Structures such as alignment apertures may then be fabricated on the surface of the substrate using photolithography techniques. Guide pins are inserted in an alignment ferrule. The carrier is placed on the ferrule the guide pins engaged with the alignment apertures. The guide pins and carrier are aligned and held in position by the alignment ferrule. The guide pins and carrier can then installed on a support block with the ends of guide pins being cemented in alignment passages within the support block. The support block provides for the guide pins, carrier and optoelectronic device to be permanently supported in accurate alignment with one another.
