In this perspective, additional bandwidth density can be achieved by integrating optical transceivers directly into the processor die. Optically enabled CPUs can provide energy-efficient, low-latency interconnects over long distances (>10m) in future data-centers. Integrated photonic interconnect technology will require sensitive and low-power receiver (RX) circuits that operate at high data rates. This work demonstrates an NRZ RX data-path implemented in 14nm FinFET bulk
