Abstract: Photonic and electronic integrated circuits can be cooled using variable conductance heat pipes containing a non-condensable gas in addition to a phase-changing working fluid. To package the heat pipe with a subassembly including the integrated circuits in a standard housing providing a heat sink contact area, the heat pipe is oriented, in some embodiments, with its axis between evaporator and condenser ends substantially perpendicular to the direction along which the integrated circuit subassembly is separated from the heat sink contact area, and a portion of the exterior surface of the heat pipe is thermally insulated, with a suitable thermal insulation structure, from the heat sink contact area.

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: In some embodiments, an apparatus includes a first optical transceiver. The first optical transceiver includes a set of optical transmitters, an optical multiplexer operatively coupled to the set of optical transmitters, and a variable optical attenuator operatively coupled to the optical multiplexer. The variable optical attenuator is configured to receive a control signal from a controller of the first optical transceiver and modulate a signal representing control information with an output from the optical multiplexer. The control information is associated with the control signal and for a second optical transceiver operatively coupled to the first optical transceiver.

Abstract: In some embodiments, an apparatus includes an automatic integrated circuit (IC) handler having a change kit. The change kit has a plunger moveably disposable onto an automatic test equipment (ATE). In such embodiments, the ATE is configured to receive an integrated circuit having an optical interface. The plunger has a first position and a second position. In such embodiments, the plunger is out of contact with the integrated circuit when the plunger is in the first position. The plunger includes an optical connector operatively coupled to the optical interface of the integrated circuit when the plunger is in the second position.

Abstract: A microcontroller can interact with external ASICs using a multi-serial peripheral interface. The ASICs and the microcontroller can be included in an electrical device or an optical-electrical device. The microcontroller can implement the interface to access the registers of the different ASICs in bulk interactions, including a bulk status request, bulk configuration setting, and bulk data reads.

Abstract: An optical transceiver can be calibrated using an internal receiver side eye scan generator, and calibration values (e.g., modulator values) can be stored in memory for recalibration of the optical transceiver. The eye scan generator can receive data from the transmitter portion via an integrated and reconfigurable loopback path. At a later time, different calibration values can be accessed in memory and used to recalibrate the optical transceiver or update the calibrated values using the receive-side eye scan generator operating in loopback mode.

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.
