摘要： An optoelectronic subassembly for use in fiber optic communications systems where multiple parallel optical fibers are used in transmitting and receiving optical signals. The subassembly is adapted for optically connecting with a ferrule and electrically connecting to a larger computing or communications system. The ferrule supports a set of optical communications fibers disposed in an array. The subassembly supports an optoelectronic device having a set of photoactive components also disposed in an array corresponding to the fiber array. The optoelectronic device is operative for either converting photonic signals to electrical signals (in a receiver) or electrical signals to photonic signals (in a transmitter). The optoelectronic subassembly includes a carrier which is precisely fabricated using photolithography techniques for aligning and supporting the optoelectronic device and photoactive components within it. The carrier further includes a precisely positioned alignment structure for cooperating with the optical ferrule to align the photoactive components of the optoelectronic device with the fibers in the ferrule when the two are interconnected. Also, the carrier may include a thin film layer and one or more alignment marks applied to the film layer for use in accurately mounting the optoelectronic device on the carrier.

摘要： 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.
