    Abstract: An interconnect transceiver for transmitting and receiving optical signals, comprising an electronics module with a transceiver engine, and a photonics module with a laser source, a modulator, a photodetector to monitor the laser, one to receive an external optical signal, and a controller to operate the laser source and the laser source modulator, an electronic switch having two states is proposed. The first state is to allow monitoring of the modulated laser source by the transceiver engine, so as to acquire a reference set of operating parameters, and the second state is where a signal from the modulated laser source is directed to the controller, such as to allow real-time control of the source of the transmitting laser and modulator by the controller.

    Abstract: Recursive optimization algorithms can be used to determine which idle photonic switching elements to configure in N×N switching fabrics to achieve crosstalk suppression. Different algorithms are used to achieve different levels of optimization. Embodiment full optimization techniques may configure all inactive cells to reduce crosstalk, and consequently may provide the best noise performance and highest power usage. Partial optimizations may configure fewer than all inactive cells to reduce crosstalk, and may provide sub-optimal noise performance at lower power usages. Differential partial optimization algorithms configure inactive cells in different stages of a photonic switching fabric. Fewer than all cells in a given stage may be configured by some algorithms.

    Abstract: There is provided an optical communication device having a silicon photonics (SiPh) component configured to perform an optical communication function; a complementary metal oxide semiconductor (CMOS) drive circuit coupled to the SiPh device for operation thereof; and one or more controllably adjustable CMOS impedance circuits coupled to the SiPh component and the electrical drive circuit. In the optical communication device, impedances of each of the CMOS impedance circuits can be adjustable over a respective limited range. The limited range may be designed and configured based at least in part on an anticipated amount of variation in electrical characteristics of the SiPh component, the CMOS electrical drive circuit, or a combination thereof. Such variation may be anticipated due to manufacturing variability.
