摘要： An optoelectronic assembly includes an optoelectronic device, housed in a transistor outline (TO) package having a base and a signal lead traversing an aperture in the base, and a circuit interconnect coupled to the optoelectronic device and TO package. The circuit interconnect substantially comprises an insulator, and includes a data signal trace, a resistor, and a conductor. The data signal trace, on a first side of the insulator, transmits data signal current between the optoelectronic device and an external device. The resistor, also on the first side, transmits the data signal current between the optoelectronic device and the data signal trace. The resistor is electrically and mechanically connected to the signal lead and to data signal trace. The conductor, on a second side of the insulator, transmits a ground current between the TO package and the external device, and forms a current path substantially parallel to the data signal trace.

摘要： The principles of the present invention relate to aligning optical components with three degrees of translational freedom. A lens pin, a lens base, and a molded package are aligned in a first direction, a second direction, and a third direction such that the signal strength of optical signals transferred between a lens included in the lens pin and the molded package is optimized. The lens pin is mechanically coupled to the lens base to fix the position of the lens relative to the molded package in the first direction. Subsequently, the lens base and the molded package are realigned in the second and third directions such that the signal strength is again optimized. The lens base is mechanically coupled to the molded package to fix the position of the lens base relative to the molded package in the second and third directions.

The ceramic platform provides the ability to house multiple electrical components and/or devices on either side of the base. The platform has a higher thermal conductivity than the base of a standard header. In addition, the platform increases the electrical input/output density of the header by increasing the number of potential electrical connections between the two sides of the base.

The optoelectronic device may include a laser diode or a photo diode. In addition, the present invention is an optoelectronic transceiver including a transmitter optoelectronic assembly and a receiver optoelectronic assembly. The transmitter optoelectronic assembly includes a transmitter TO package and a transmitter circuit interconnect, and the receiver optoelectronic assembly includes a receiver TO package and a receiver circuit interconnect.
