Abstract:
An optoelectronic subassembly for interconnecting a plurality of optical communications fibers supported in an optical ferrule to an optoelectronic device having a plurality of photoactive components, said optoelectronic subassembly comprising:a silicon substrate carrier adapted to support the optoelectronic device and including an alignment structure for cooperating with the optical ferrule to align the optical fibers with the photoactive components of the optoelectronic device when the subassembly is connected to the optical ferrule and one or more alignment marks placed on said carrier and precisely aligned relative to the alignment structure so that when the optoelectronic device is positioned with reference to the alignment marks the photoactive components will be precisely aligned with the optical fibers upon interconnection of the subassembly with the optical ferrule, and wherein said alignment structure is etched into said silicon substrate carrier using photolithography techniques.
