摘      要：A 4×112 Gb/s hybrid-integrated optical receiver is demonstrated based on the silicon-photonic vertical p-i-n photodetector and silicon–germanium transimpedance *** propose a photonic-electronic co-design technique to optimize both the device-level and system-level performance,based on the end-to-end equivalent circuit model of the ***-time linear equalization and shunt peaking are employed to enhance the frequency *** results reveal that the optical-to-electrical 3-dB bandwidth of the receiver is 48 *** open NRZ eye diagrams at56 Gb/s and PAM-4 eye diagrams at 112 Gb/s are achieved without an equalizer in the *** measured bit error rates for 56 Gb/s in NRZ and 112 Gb/s in PAM-4 reach 1×10^(-12)and 2.4×10^(-4)(KP4-FEC:forward error correction)thresholds under-4 dBm input power,***,the proposed receiver boasts a power consumption of approximately2.2 pJ/bit,indicating an energy efficient solution for data center traffic growth.
