The silicon photonic technology is still young and only recently emerging for commercial systems adoption. Optical interconnects based on silicon photonic devices have the potential to deliver huge amount of bandwidth at low energy and cost. Understanding the capacity limits of these interconnect is of vast importance. In this paper, we present a design and modeling approach for obtaining the maximum achievable aggregate bandwidth in a silicon photonic link with microring modulators and filters. It is based on a uniquely comprehensive modeling platform for efficiently exploring the design space of silicon photonic interconnects, from the physical layer to the link-level analysis. We concentrate our efforts on microring-resonator-based links, as they have the lowest footprint among the current most developed silicon photonic interconnect devices. Furthermore we derived the optimal device parameters. We obtained an upper bound on the maximum aggregate throughput achievable with a microring-based silicon photonic link. This is of paramount importance for link designers, informs device designer for optimal parameters and also can allow comparison with other existing and future devices.
