该论文提出了一种基于模拟域处理的DP-QPSK相干光接收机，在28nm CMOS工艺下实现了200Gb/s的数据速率和4.6pJ/b的能效，解决了传统ADC-DSP方案在短距光互连中功耗过高的问题。
cloud computing, have significantly driven the requirement for high transmission data rates. Polarization diversity coherent detection is an indispensable technique for realizing high-capacity transmission owing to its excellent spectral efficiency. ADC-DSP-based coherent receivers [1-2] have been widely deployed in long-haul optical systems, but the high power consumption prohibits their application in power-sensitive short-reach links like 5G mobile backhaul networks, arousing eagerness for power-efficient analog solutions. An analog coherent receiver is proposed in [3], where a single-stage equalizer is used to compensate for chromatic dispersion (CD) and rotation of state of polarization (SOP), resulting in complex interconnection, large parasitic capacitance, and consequently limited data rate.
