—Recent advances in nanophotonic fabrication have made the optical network-on-chip an attractive interconnect option for next-generation multi-/many-core systems, providing high bandwidth and power efficiency. Both post-fabrication and runtime calibration of the optical components (ring resonators) are essential to building a robust optical communication(More)
On-chip optical communication infrastructure has been proposed to provide higher bandwidth and lower power consumption for the next-generation high performance multi-core systems. Online calibration of these optical components is essential to building a robust optical communication system, which is highly sensitive to process and thermal variation. However,(More)
