Complementary Polarization-diversity Self-Coherent Homodyne Receiver with Rapid Polarization Tracking for Remote LO

We propose a complementary polarization-diversity coherent receiver (C-PDCR) based on complementary polarization detection. The proposed C-PDCR features rapid polarization tracking for remote LO using electronic DSP. The robustness is verified by a 1.08-Tb/s dual-polarization PCS-256QAM signal with up to 314-Krad/s polarization tracking speed. © 2022 The Author(s)
