摘要： A transceiver assembly for use in fiber optic communications systems where multiple optical fibers are used in transmitting and receiving optical signals. The assembly is adapted for being mechanically and optically connected with a ferrule supporting a set of optical communications fibers. The transceiver assembly supports an optoelectronic device having a corresponding set of photoactive components which are operative for either converting photonic signals to electrical signals (in a receiver) or converting electrical signals to photonic signals (in a transmitter). The transceiver assembly includes a frame section having a carrier which is precisely fabricated for supporting the optoelectronic device and includes an alignment structure for cooperating with the optical ferrule to align the photoactive components with the fibers in the ferrule. The frame section is part of a larger carrier assembly including a multilayer circuit board which may include a microcontroller chip, an edge connector for electrically connecting with a computer or communications system and a flex circuit which provides communications lines linking the frame section, circuit board and edge connector.

摘要： A lens array for use in fiber optic communications modules where multiple optical fibers are used in either transmitting or receiving optical signals. The lens array is adapted for optically interfacing a set of photoactive components such as semiconductor lasers or photo diodes deployed on an integrated circuit chip with a set of optical communications fibers supported in a ferrule. The individual lens elements within the array are shaped to have a greater height than width and are fitted together by being truncated along their boundaries with adjoining lenses. The increased height of the lens elements allows them to gather and transfer more light between the photoactive components and the optical fibers.

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.
