High-Speed Optical Interconnects

Project Description

This goals of this research are to develop robust energy-efficient transceivers for a unified inter- and intra-chip photonic interconnect architecture based on integrated ring resonator modulators and waveguide photodetectors. To accomplish this goal, research objectives are: (1) develop a system-level optimization framework for designing transformative photonic on-chip networks and inter-chip links; (2) implement and test novel nanometer CMOS prototypes of the proposed photonic interconnect transceivers; (3) develop low-complexity digital control loops for optical element tuning.
