    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.

    Abstract: An optical device comprises a transmitter module, a receiver module, and a switch comprising a first port coupled to the transmitter module, a second port coupled to the receiver module, a third port configured to couple to a transmitter fiber, and a fourth port configured to couple to a receiver fiber. A method implemented in a switch, the method comprising operating in a monitor mode that provides for monitoring of a transmitter fiber or a receiver fiber, receiving a command to transition from the monitor mode to a data mode, connecting a transmitter module to the transmitter fiber, and connecting a receiver module to the receiver fiber.

    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.
