    摘要： A circuit package includes a circuit substrate having a cutout portion defined therein, an interconnect electrically coupled to the circuit substrate and an active circuit component disposed off the circuit substrate within the cutout portion and electrically coupled to the interconnect. An optical circuit includes a lead frame and an optical component electrically coupled to the lead frame. The lead frame includes a first lead portion at a first level having an upper surface and a lower surface, and a second lead portion at a second level lower than the first level and electrically connected to the first lead portion. The lower surface of the first lead portion is arranged to electrically connect to a surface of a circuit substrate. The second lead portion includes an upper surface and a lower surface. The optical component is disposed on the upper surface of the second lead portion.

    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 frame section includes a flex circuit layer, a support layer, and a silicon substrate carrier. The flex circuit layer includes a plurality of communication lines and having a flex circuit window section. The support layer includes a support layer window smaller that the flex circuit window section so as to define an inwardly extending support shelf. The silicon substrate carrier is mounted on the support shelf in the support layer window and includes an optoelectronic device supported on the silicon substrate carrier. The optoelectronic device includes a set of photoactive components. The frame section is used for supporting the optoelectronic device within a fiber optic transceiver assembly which in turn is used for connecting to a fiber optic ferrule supporting a set of fiber optic communication fibers.

    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.
