摘要： Flexible printed circuit boards interconnect to adjacent electronic devices through one or more of high speed data, low speed data, high current, and ground lines and pads. The design of the high speed data pads and traces and adjacent ground pads and traces maintains a desired impedance in the flexible circuit and at the transition from the flexible circuit to a printed circuit board, a ceramic header, or other device to ensure high speed operation. The pads are preferably arranged in a two dimensional geometry such that a connecting area of the flexible circuit is narrower than it would preferably be if the pads were arranged linearly. The two dimensional array also allows the use of the high current thermoelectric cooler pads, which require large surface areas that may otherwise not fit in a conventional linear array.

摘要： A small form factor transceiver module that incorporates an externally modulated laser (EML). The transceiver module has a transmitter optical subassembly with a header assembly having a base with a platform extending through. The platform has a plurality of conductive traces extending through the platform for making connections on both sides of the base. A thermoelectric cooler (TEC) is used to dissipate heat from a laser within the header assembly. The TEC dissipates heat sufficiently to allow the EML to be used in the header assembly. In this manner, EMLs can be used in relatively small optical devices, including small form factor transceivers that comply with the XFP standard. The XFP modules with EMLs can be used for longer links than XFPs without EMLs. In addition, EMLs can be stabilized using TECs so that XFP modules can be used for DWDM-type applications.

摘要： An improved monitoring and control system for a laser in a header assembly of a transmitter optical subassembly (“TOSA”) is disclosed. The monitoring and control system, includes one or more monitor photodiodes (“MPDs”), is positioned together with the laser on a component submount. The submount in turn is mated with a multi-layer platform (“MLP”) that forms part of the header assembly. The MLP hermetically extends through the header assembly to provide a plurality of electrical interconnects for the laser, MPD(s), and other submount components. In one embodiment, a single MPD is located proximate the laser to receive back facet laser light emission. Measurement of the back facet emission enables the MPD to determine laser intensity. In another embodiment, two MPDs are joined together to receive the back facet laser light emission. Comparison of each MPD's measurement enables the laser's wavelength to be determined and adjusted to optimize its performance.

摘要： A header assembly including a base and a platform extending through the base and substantially perpendicular thereto. The platform includes conductive pathways that connect electrical components on either side of the base, and the conductive pathways cooperate to form a connector at the first end of the platform. A laser is mounted on top of a thermoelectric cooler that is directly joined to the second end of the platform. The laser and thermoelectric cooler are enclosed in a hermetic chamber cooperatively defined by the base, the platform, and a cap that is joined to the base. A photodiode optically coupled with the laser and a thermistor thermally coupled with the laser cooperate with the thermoelectric cooler and a control circuit to facilitate control of the performance of the laser.

摘要： A multi-layer feedthrough structure for use in optoelectronic equipment. The feedthrough structure is composed of multiple stacked ceramic layers that together form a multi-layer platform. The multi-layer platform bisects the base portion of a header assembly that is located within the transmitter optical subassembly such that an interior portion of the multi-layer platform is located within the header assembly and an exterior portion is disposed outside. Each layer contains at least a portion of a plurality of conductive pathways that extend from the exterior to the interior portion of the multi-layer platform. A top insulating layer enables the conductive pathways to pass from the exterior to the interior portion of the platform without electrically contacting the header assembly base. The conductive pathways serve as electrical interconnects between components located within the header assembly and structures outside thereof.
