    摘要： Semiconductor lasers are aged to identify weak or flawed devices, resulting in improved reliability of the remaining devices. The lasers can be aged using a high-power optical burn-in that includes providing a high drive current to the lasers for a period of time, and maintaining the ambient temperature of the lasers at a low temperature. After the high-power optical burn-in, the output of the lasers can be measured to determine if the lasers are operating within specifications. Those that are not can be discarded, while those that are can be further aged using a high-temperature thermal burn-in that includes providing a drive current to the lasers while maintaining the ambient temperature of the lasers at a high-temperature.

    摘要： An electromagnetic shielding configuration comprising a first electrically conductive wall having a first surface and a second electrically conductive wall having a second surface. The first surface is oppositely disposed from the second surface, wherein interfacing of the first conductive wall and the second conductive wall forms an enclosure wall. The first surface comprises at least one stepped edge forming a plurality of surfaces of unequal lateral displacement, and a corrugated surface on at least one of the plurality of surfaces, the corrugated surface formed by a series of apices extending radially from the first surface. The second surface is substantially a conjugate of the first surface.

    摘要： Chip identification pads for identification of integrated circuits in an assembly. In one example embodiment, an integrated circuit (IC) assembly includes a controller, a plurality of ICs, a shared communication bus connecting the controller to the plurality of ICs and configured to enable communication between the controller and each of the plurality of ICs, and a set of one or more chip identification pads formed on each IC. Each set of chip identification pads has an electrical connection pattern. The electrical connection pattern of each set is distinct from the electrical connection pattern on every other set. Each distinct electrical connection pattern represents a unique identifier of the corresponding IC thereby enabling the controller to distinguish between the ICs.

    摘要： A DPSK/DQPSK receiver includes an optical splitter that separates the received DPSK/DQPSK optical signal according to an optical power splitting ratio into a plurality of received optical signals. A plurality of optical filters passes a plurality of filtered received optical signals. A plurality of optical detectors generates a plurality of electrical detection signals, each with a power that is related to a power of a respective filtered optical signal. A plurality of amplifiers generates a plurality of amplified electrical signals. At least one electrical signal combiner combines the plurality of amplified electrical detection signals generated by the plurality of optical amplifiers into a combined reception signal.

    摘要： An optical transceiver configured to perform calibration of digital diagnostics prior to providing the calibrated values to a host computing system (hereinafter referred to simply as a "host") that is communicatively coupled to the optical transceiver. The optical transceiver includes a sensor that measures an analog operational parameter signal such as temperature or supply voltage. Each analog signal is then converted to digital samples by analog to digital converter(s). A processor executes microcode that causes the optical transceiver to perform calibration on the various samples to compensate for predictable error introduced into the analog signal prior to or during the analog-to-digital conversion. The optical transceiver may then make the calibrated result accessible to the host.
