    Abstract: In some embodiments, an apparatus includes an optical transmitter module that can be electrically coupled to an electrical serializer/deserializer and a controller. The optical transmitter module can include an electrical detector that can receive an in-band signal. The electrical detector can send to the controller a first power error signal and a second power error signal based on the in-band signal. The controller can send a correction control signal to the electrical serializer/deserializer based on the first power error signal and the second power error signal such that the electrical serializer/deserializer sends a pre-emphasized signal to the optical transmitter module based on the correction control signal. In such embodiments, the first power error signal, the second power signal and the correction control signal are out-of-band signals.

    Abstract: An optical pick and place machine that includes a self-calibrating optical controller for error feedback based optical placement of optical components using active alignment is described. The optical controller can include a loopback mode to generate a baseline value of light generated by a light source and measured by a photodetector within the optical controller. The optical controller can further include an active alignment mode in which the light is coupled from the pick and place machine to the optical device on which the component is placed. The optical coupling of the placed component can be evaluated against the baseline value to ensure that the optical coupling is within specification (e.g., within a prespecified range).

    Abstract: A hybrid automated testing equipment (ATE) system can simultaneously test electrical and optical components of a device under test, such as an optical transceiver. The device under test can be a multilane optical transceiver that transmits different channels of data on different lanes. The hybrid ATE system can include one or more light sources and optical switches in an optical test lane selector to selectively test and calibrate each optical and electrical components of each lane of the device under test.

    Abstract: A hybrid optical-electrical automated testing equipment (ATE) system can implement a workpress assembly that can interface with a device under test (DUT) and a load board that holds the DUT during testing, analysis, and calibration. A test hand can actuate to position the DUT on a socket and align one or more alignment features. The workpress assembly can include two optical interfaces that are optically coupled such that light can be provided to a side of the DUT that is facing away from the load board, thereby enabling the ATE system to perform simultaneous optical and electrical testing of the DUT.
