摘要

长途和城域链路的光通信技术正在经历向相干技术和高频谱效率调制格式的过渡，如双极化(DP) QPSK、DP- qam和OFDM。相干解调和DSP的结合使得用于补偿光纤缺陷(如色散(CD)和偏振模色散(PMD))的昂贵的光信号处理硬件被基于DSP的技术所取代[1]。经济大规模部署相干系统需要集成CMOS技术中的光收发器功能。

A 40nm CMOS single-chip 50Gb/s DP-QPSK/BPSK transceiver with electronic dispersion compensation for coherent optical channels

Optical communication technology in long-haul and metropolitan links is experiencing a transition to coherent techniques and high spectral efficiency modulation formats such as dual-polarization (DP) QPSK, DP-QAM and OFDM. The combination of coherent demodulation and DSP allows costly optical signal-processing hardware used to compensate fiber optic impairments such as chromatic dispersion (CD) and polarization-mode dispersion (PMD) to be replaced by DSP-based techniques [1]. Economic large-scale deployment of coherent systems requires the integration of the optical transceiver functions in CMOS technology.
