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.
