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 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: An optical receiver can implement a transimpedance amplifier (TIA) to process received light using a closed loop optical pre-amplification. The optical receiver can use an average input value of the TIA to control an semiconductor optical amplifier (SOA) or pre-amplification as received average signal varies. The optical receiver can include a gain controller for the TIA that can measure the TIA swing to adjust the gain of the SOA to pre-amplify received light in a closed loop control configuration.
